Purpose: Used to define non-torsionally resistant hinges in Girder System Projects.
--> Given in girder system input
HTR-i data is used to tag hinges that do not transfer torque. HTR-i is a list of “zeroes” and “ones” for hinges on girder “i” where the nonzero value indicates the particular hinges that do not transfer torque. For example, if there were three hinges on girder 1 and only the second hinge was allowed to transfer torque the data would be HTR-1 1 0 1 (If HTR-i data is not given hinges will be assumed to transfer torque).
