MDX Software - Problems Fixed

Software changes are run through a test suite of approximately 50 bridge projects to determine how much impact such changes might have to a variety of project parameters. Prior to March 1, 2010 only those significant fixes that could cause overstressing or significant changes to deflections (defined as Class 1 below) as determined by the results of this test suite had been listed. Minor fixes, i.e. those that did not significantly affect the example projects in the test suite, were only being reported to the user who reported the problem. Beginning March 1, 2010, the Fixlog includes entries for coding adjustments involving minor changes (defined as Classes 2 and 3 below) to assist users in deciding whether or not to apply updates based on minor fixes:

7/17/19 Class 1 - Fixed problem with the recent rigid links additions where not all the slab plate elements were being generated in some plate and eccentric beam projects (which had removed deck stiffness, artificially raising composite deflections, and the resulting postprocessing for the member effects then were based on higher deflections, which artificially raised the member forces, etc.) [6.5.4215]
6/20/19 Class 2 - Fixed issue with sidewalk stresses sometimes not being included in flange stresses at splice locations. [6.5.4189]
6/19/19 Class 1 - Fixed issue with generating unbraced length data (BR) in girder inputs in girder system analysis that could occur and which was recently caused by the transition to using rigid links in the girder system analysis bracing modeling. [6.5.4188]
6/19/19 Class 2 - Fixed allowable stress/ratings issues at splice locations near inflection points in LFD projects [6.5.4188]
3/13/19 Class 2 on LRFD line girder projects with hinges: hinge locations in the analysis were correct, but the reactions table was acting as if it was at a different location when calculating the reaction on the hinge. [6.5.4090]
3/12/19 Class 1 on LFD projects: A few fixes have been made on LFD projects regarding: box girder allowable stresses at splices, top and bottom flange overload stress tables, overload ratings tables, and NONCOMPOSITE girders. [6.5.4089]
2/14/19 Class 2 - Fixed issue with LRFD Shear Connectors table required pitch calculation at and near supports where it was sometimes using n=1 instead of n=1.5 to determine the Max Pitch. Fixing this problem resulted in a lower Max Pitch at or near supports in some situations. [6.5.4063]
2/6/19 Class 3 - Fixed issues occurring on LRFD Top and Bottom Permanent Deflection Control Stress tables.[6.5.4054]
12/18/18 Class 1 - Fixed a problem occurring when STP-i type "7" method was used to designate integral supports. Since this would effect end supports more significantly than piers, it was a "Class 1" problem in the context of integral end supports using STP-i 7's. (Other forms of integral supports were unaffected, e.g. ITGSUP, KMB-i, or INTEGRAL ABUTMENTS.)[6.5.4005]
12/13/18 Class 2 - Fixed a problem in sharply skewed parallel/concentric girder system projects where the girders on the opposite side from girder 1 could have some anomolies in moments and shear. [6.5.4000]
12/8/18 Class 2 - Fixed a problem where bending strength was not using the web thickness for the right location, in a situation where the web thickness was varied frequently. [6.5.3982]
11/8/18 Class 1 - Fixed a problem in girder system projects where sidewalk located with SWLOC2 could have been instead using the offset given by SWLOC1. The significance of this problem would depend on how different these distances were, so this is being classified as Class 1 in that context. [6.5.3965]
11/8/18 Class 3 - Fixed a problem in LFD projects where allowable fatigue stresses were not considering noncomposite regions established by COMSPC. [6.5.3965]
11/8/18 Class 1 - Fixed problems in LFD projects with: (1) factored shears, (2) factored reactions in LFD projects sometimes not flagging and/or showing the amount of uplift per 3.17(a). (Note: The program takes the conservative assumption of not including composite dead loading in this calculation, although this can be included with the INCLUDE COMPOSITE DEAD LOAD IN UPLIFT CHECK condition.), and (3) incremental service shears. [6.5.3965]
11/8/18 Class 3 - Fixed a problem in LFD projects where allowable fatigue stress not considering noncomposite regions established by COMSPC [6.5.3965]
10/16/18 Class 3 - Fixed a graphical display issue that could occur in general geometry girder system projects. (Live loading is according to the wheel locations shown in the girder system output which were unaffected and so this problem was only a graphical display issue.) [6.5.3942]
10/15/18 Class 3 - Fixed a minor issue with the shear connector counting in the Shear Connectors report in LRFD projects.[6.5.3941]
10/9/18 Class 2 - Fixed some issues with LFD girder ratings where at some locations the program was not correctly calculating ratings and/or displaying the capacity and the governing flange for the ratings.[6.5.3935]
10/9/18 *********************************************************
* NOTICE OF CHANGE TO PROGRAM DEFAULT BEHAVIOR *
*********************************************************

The IGNORE MOMENT SHIFTING condition has now been adopted as the new default program behavior for LFD projects (and ALLOW MOMENT REDISTRIBUTION is available to allow the program to redistribute moments at pier when the section is compact. Note: this was already switched for LRFD projects on 8/17/18.) [6.5.3935]
9/27/18 Class 2 - Fixed issues with LRFD line girder projects: (1) having to do with permit truck shears, and (2) dead load shears when concentrated dead loads were present. [6.5.3923]
9/27/18 Class 3 - Fixed issue in LRFD line girder projects having to do with permit truck moments and shears being based on applying the dist factor to the axle load at the axle's location instead of using the dist factor that is at the effect location. (Note: this would only be an issue with varying dist factors. along the girder.) [6.5.3923]
9/6/18 Class 3 - Fixed a problem with DETAILED CALCS FOR SHEAR STRENGTH report in LFD projects. [6.5.3902]
8/18/18 Class 3 - Fixed a problem with ASD ratings when pouring analysis was involved in the run. [6.5.3883]
8/15/18 Class 2 - Fixed a problem with Service II ratings for the default girder ratings method in LRFD projects where the some calculations being considered had the sign wrong on the dead load components of the calculation, sometime resulting in a lowering of Service II ratings after the fix. (Problem did not occur in the LRFR RATINGS). [6.5.3881]
8/15/18 Class 2 - Fixed a problem that could occur at Bottom Flange Allowable stresses at bottom flange splices in Noncomp Dead Wet Concrete Stress tables. [6.5.3881]
8/14/18 Class 1 - Fixed problem in LRFD box girder projects using INTEGRAL ABUTMENTS. The problem was with Bottom Flange Factored Bending Stresses and Ratings sometimes assuming bottom flanges were stiffened when bottom flange stiffeners were not specified (however, the Factored Strength table values and its perfomance ratios were using on the correct bottom flange allowable stresses.) [6.5.3878]
7/12/18 Class 2 - Fixed issue with the IL-120 reactions without impact shown in girder Case Data report. [6.5.3846]
7/11/18 Class 3 - Noncomposite dead load bottom flange factored bending stresses when these included pouring sequence analysis were sometimes double multiplying (instead of removing as it should have been) TFORMFCT when the REMOVE FORMS AFTER EACH POUR was being used. [6.5.3845]
6/22/18 Class 1 - (FOR REACTIONS THAT INCLUDE SIDEWALKS)- Fixed an issue in girder output of LRFD girder system projects where the reactions listed for interior supports were not including the sidewalk reactions when straddling trucks governed at the interior reactions. (Girder system output reactions were reporting these properly as these are shown in a separate column there.) [6.5.3827]
5/31/18 Class 2 - Fixed an issue in LRFD projects in rating calculations at splices where it was using the allowable stress at the tenth pt on the side of the splice instead of using the allowable stress at the specific location of the splice.[6.5.3804]
5/4/18 Class 1 - Fixed situations in ratings of curved girders where lateral bending stresses were not being considered in rating calcs even though lateral bending stresses were being used in flange factored bending stresses.[6.5.3777]
4/4/18 Class 2 - Fixed two issues with ratings calculations at splices: (1) where it was sometimes using negative moment capacity instead of positive moment capacity on a compact section, and (2) where it was sometimes using the steel from the other side of the splice in a hybrid girder.[6.5.3747]
3/29/18 Class 1 - Fixed two issues with concurrent reactions in LRFD girder system projects: 1) in some cases when the governing main reaction for interior piers was for the 0.9(straddling truck+lane) case, the concurrent reactions were being shown for the lane+truck case, 2) IL-120 DESIGN TRUCK concurrent reactions were not including the lane loading.[6.5.3741]
3/23/18 Class 1 - Fixed a problem with LRFD line girder projects where the lane fractions for deflections calculated by the program were sometimes accounting for multiple presence factor when there were greater than two lanes, which led to a reduction to the lane fraction for deflection. AASHTO 2.5.2.6.2 suggests this be simply calculated as number of lanes divided by number of beams. (The exception to this is that the multiple presence factor of 1.2 will be conservatively applied when there is only one lane, which has been requested by users in the past.) Alternatively, the lane fraction for deflection can be specified by the user with LANED in line girder projects (LD-i in girder system projects).[6.5.3735]
3/15/18 Class 1 - Fixed a problem with line girder projects using IL-120 DESIGN TRUCK where the reactions from 0.9(straddling trucks+lane loading) were not always including the lane loading portion. [6.5.3727]
3/8/18 Class 2 - Fixed some problems with LRFD project shear capacities used for rating at supports or splices where the program was sometimes switching left and right side capacities or the right side capacity sometimes using the higher of the intermediate transverse web stiffener spacings on either side of the support instead of only using the spacing to the right side of the support. [6.5.3720]
2/26/18 Class 2 - Fixed problem that could occur in LRFD projects using the LRFR RATINGS condition where the program was not accounting for sidewalk loading in shear ratings calculations. Bending ratings and performance ratios of factored stresses and factored strengths were unaffected by the problem. [6.5.3710]
2/19/18 Class 1 - for general girder system projects with severely skewed supports and curved lanes in combination

Class 2 - for all other general girder system projects, when lanes are defined instead of specifying distribution factors for live load analysis.

The wheel location routines in the program were updated to better handle combinations of severe skews and curved lanes. Depending on the severity of the skew and curved lanes in combination in the same regions, Wheels were sometimes getting bunched closer together in lanes and consequently trucks were sometimes getting spread apart in regions of severe skew and curved lanes, and although these symptoms could have somewhat offsetting effects, an overall redistribution of live load effects among girders in such regions could have occured as a result. The wheel locations tables in the girder system analysis output indicate where the live load is being placed, subject to the convention of the ROADWG input for general geometry projects. Effects are likely to be moderate or minor for non-severe skews. Note: this issue may also have led to cases where the program was unable to determine whether or not there was room enough for the lanes to be floated in general geometry projects, causing the user to have to turn to the distribution factor approach, whereas the updated version of the program might now allow the lanes to be defined and floated on such projects. [6.5.3703]
1/18/18 Class 3 - Fixed run termination which was happening when SLABXR and SLABXL were being used due to a recent input rule having been implemented based on the more common SLABEXT. [6.5.3671]
1/18/18 Class 2 - (Followup on 1/9/18 IL-120 issue). Some situations of the factored moment being elevated for some tables also were fixed as an additional aspect of this issue. [6.5.3671]
1/9/18 Class 2 - Possibility of IL-120 DESIGN TRUCK live load moments and flange stresses being calculated too high.

The problem occurred differently in line girder projects than in girder system projects.

In Line Girder Projects:
The truck+lane case was sometimes considering the lane twice in the service moment table but flange stress calcs generally were correctly based on correct governing moment, except sometimes for the stresses at splices which could have been using the inflated moment that the problem had created.

In Girder System Projects:
While truck+lane case was showing up correctly in girder system output, the truck+lane case in the girder rating output was sometimes considering the lane twice, and when that did occur the flange stress calcs in general then could have been calculated too high as a result of the inflated moment that the problem had created.

[6.5.3662]
12/29/17 Class 3 - Fixed issue with the reporting of Overload Rating Capacities in LFD projects (Overload Ratings were unaffected.) [6.5.3651]
12/29/17 Class 3 - Fixed issue with COMSPC composite stiffnesses in computing LL deflections in LFD projects. [6.5.3651]
12/7/17 Class 1 - Fixed issue with LFD compactness determination, and also fixed issue with how LIMIT TO ELASTIC STRENGTH (and LIMIT NEG MOM REGIONS TO ELASTIC STRENGTH) work in LFD. In the process the DETAILED CALCS FOR COMPACTNESS report generation was overhauled. [6.5.3629]
11/17/17 Class 3 - Fixed issue with tandem truck positive moment sometimes being calculated too high in girder system projects in very short spans due to influence surface interpolation routine not tracking downward past a neighboring hump on the surface when spans were less than 20 feet. For typical span lengths the effect of the program recoding on the tandem truck moment should have only minor effects (< 1 % ). [6.5.3608]
11/11/17 Class 3 - Slab tension stresses were using noncomposite section properties for negative moment pouring increments as a result of some recoding several months ago, which generally had the effect of amplifying slab tension stresses, instead of using composite section properties to determine these stresses. [6.5.3602]
11/8/17 Class 3 - Fatigue stress checks at ends of some longitudinal stiffeners were sometimes not being listed in fatigue stress output. [6.5.3599]
10/26/17 Class 3 - Fixed issue where flange factored bending stress performance ratios at splices were always based on strength for compact setions instead of showing ratio based on stress when that was lower. [6.5.3587]
10/15/17 Class 2 - Fixed issue with how WHEELR applies to shear at supports in LFD line girder projects. [6.5.3576]
10/12/17 Class 3 - Fixed issue in LFD projects having to do with shear strength ratings, and some overload bending and shear ratings mainly near splices. [6.5.3573]
10/4/17 Class 1 - Fixed Issue affecting moments and shears in line girder projects with trucks with 5 or more axles (including the IL-120 DESIGN TRUCK). It is particularly more of an issue the more axles there are on the truck. This issue appears to have been caused by some new coding earlier this year and was just recently reported. [6.5.3566]

7/28/17 Class 3 - Fixed program crash sometimes happening for cover plates. [6.5.3496]
7/26/17 Class 3 - Fixed a few Service rating calculation issues which were mostly occuring at splice locations. [6.5.3494]
7/16/17 Class 3 - Tandem Truck moments in girder system projects in some cases was using a 0. axle spacing which was slightly increasing moments. Shear and reactions did not have this problem. [6.5.3486]
7/13/17 Class 1 - Fixed issue with MLFACTORS if first value of MLFACTORS was given as less than 1.1, which was triggering the SINGLE LANE LOADING command, causing live load effects to come from only one lane. [Note: The MLFACTORS command isn't intended to be used as a method to scale the live load overall but instead to allow some specific variations of these factors that some state DOTs were doing. This has been modified to allow the first value to be down to 1.001 to make the MLFACTORS command more flexible, but its intended use is for allowing logical relative adjustments to how the amounts of the lanes are to be combined.] [6.5.3482]
7/10/17 Class 1 - The cover-plated/noncover-plated regions of rolled beams weren't always being detected right at locations in determing Cb. [6.5.3478]

8/7/04 Effect on reactions of concentrated dead loads in system analysis.
8/7/04 Straight girders in a grid consisting of both straight and curved girders were not using the 2003 curved girder specifications for fatigue.
(4/26/04-7/15/04) Add following paragraph to the description for the condition NO BRACING ALONG PIERS:

"If radial bracing crosses the pier line (parallel/concentric model), suggest omitting such bracing from the input file until the layout has been generated. Then use ADDMEM to insert the omitted braces."

(4/26/04-7/15/04) Allowable of .55Fy (eg., 27.5) used in ASD rating table instead of the value shown in Table 10.32.1A (eg., 27.0).
(4/26/04-7/15/04) Problem with Mn of (6.10.4.2.2a-2) limiting Mn of (6-10.4.2.2a-3) for compact positive moment region where piers are noncompact. (LRFD)
(4/26/04-7/15/04) Slab overlays (SLBOVR) automatically were being added to WSDL data in line girder projects, which is counter to Help section (manual) descriptions. This has been reversed and a warning message generated that overlay weight should be included in WSDL. Slab overlay in system projects correctly has been not included in WS-i, conforming to the Help section description. A warning message now is being generated as reminder that slab overlay weight should be included in WSDL (line girder) and WS-i (girder sysems).
