Effect of Pylon Shapes on Seismic Response of a Long-Span Steel Box-Girder Cable-Stayed Bridge

In recent decades, the demand for complex and economical engineering structures with great aesthetics has been on rise cable stayed bridges also take their share of this interest. Besides many advantages cable-stayed are quite flexible, hence susceptible mainly to dynamic actions such as impact loads, wind effects seismic excitations. context, study focused effect A H shape reinforced concrete pylons behavior a long span steel triple box-girder bridge that was presumed be located in an earthquake-prone region Turkey. The 3D models were constructed using SAP2000 software time history analysis have carried out considering sag, large displacement effects. responses compared terms axial force cables, deflections deck
