Abstract

Performance of bridges with elastic pad bearing is weak in earthquakes. On 2004 Sumatra earth quake Chengappa bridge in Andaman suffered from the dislocation of bridge. This study examine the structural performance of Chengappa bridge with and without dampers. In first model examine the seismic effect of linear bridge with and without damper. In second model seismic effect of double curved bridge is examined with and without damper. Finite element models were developed, time history analysis and dynamic analysis performed using ANSYS to assess the structural performance of these bridge. The dimensions of the bridge used for the analysis taken same as the chengappa bridge for both linear and non-linear effects. Structure were analysed under GM3 earthquake loading. Time period, deck displacement, base shear and acceleration investigated
