Hinges

The program creates Caltrans hinges for bridge seismic design request, but Caltrans hinges are only available for Section Designer section, regular rectangular sections or circular section. Therefore, the column section should be one of the sections for which Caltrans hinges can be generated.

Pushover Analysis

Sometimes, the pushover analysis may not get completed, because the structure is being pushed beyond its capacity and it becomes unstable, thus causing numerical problems and the analysis being terminated prior to reaching the full target displacement. However, the calculated pushover capacity displacements are still correct, because they are automatically identified from the pushover curve just before the strength loss.
