| Abstract: |
In this research, the effects of moderate earthquakes on bridges of Department of Rural Roads which were not specifically designed to withstand earthquakes are investigated. Components in the study includes seismic hazard analysis, classifications of bridges of Department of Rural Roads, cyclic loading tests of 0.40 m x 0.40 m RC columns, cyclic loading tests of bearings, seismic downhole tests to measure shear wave velocity for site classification, and seismic response analysis of bridges. From cyclic loading tests of columns, the ductility capacity of the RC bridge column detailed according to the current practice is found to be 4.0. A series of analysis are conducted on 16 bridge models. Piers with 0.35 m x 0.35 m and 0.40 m x 0.40 m sections in bridges with a span length of 10m or less are found to be vulnerable to earthquakes because of a high ductility demand. |
