The modeling and seismic analysis of bridge structures have been a major evolution over recent decades linked directly to the rapid development of digital computing. In past, elastic analysis procedures used for bridge structural assessment which is not sufficient for the inelastic performance evaluation of structure when subjected to hazardous seismic forces. Nonlinear dynamic analysis become essential for bridges structural assessment however, it’s costly consuming. For that, nonlinear static analysis (pushover) becomes preferable inelastic seismic behavior tool in structural evaluation of bridges because of its low costs and time consuming. A three-dimensional finite element of nonlinear pushover analysis for short span Reinforced Concrete (RC) bridge with circular piers cross section is modeling to present effects of soil structural interaction (SSI) using SAP 2000 as a finite element tool. Structural element models are including linear foundation springs modeling, and nonlinear RC piers modeling. In this study the SSI effects of nonlinear pushover analysis of short span RC bridges to determine the significant effects on seismic characteristics, displacement capacity and performance of short span RC bridges. In this comparative analysis considering nonlinear static pushover Analysis for different SSI of Hard soils, Medium soil, Loose soils according to I.S. 1893-2016.
