Abstract

A large portion of modern infrastructure involves the construction of irregular shapes of structures. In the design of bridges this is a considerable problem to provide substructure irregularity in the structure. In this report we are using Csi Bridge 2016 for performing non-linear pushover seismic analysis of substructure irregularity with solid and hollow pier sections. We perform design of the structure and their numerical analysis where we get shear and displacement values for different aspect ratio. The results obtained from the analysis shows that the vernability of the structure due to base shear goes on increasing as increasing the substructure irregularity for both solid and hollow pier section. As the substructure irregularity increased there will be a decrement in displacement capacity of the bridge structure for both solid and hollow pier section. Therefore we can say that the performance of hollow pier sections are much better than the solid pier section in case of substructure irregularity and could be a better option as compare to solid piers.
