Seismic Response Analysis of Multispan Bridge Using FEM
Simply supported bridges are common bridges in China which have exhibited considerable vulnerabilities in past earthquake events. This paper takes a bridge in BaoTou as a case, by means of the FEM software MIDAS/CIVIL. Elastic response spectrum analyses are conducted for this bridge with different span lengths, number of spans, and pier height. The results show that bridges with the same length but divided into a smaller number of spans are found to be more vulnerable to earthquake excitations than those with larger number of spans. Increasing span length is also found to have a negative impact on the seismic capacity of the bridge. Also, the height of the piers may add to the risk of damage to the bridge during an earthquake. This study will serve as a reference to another bridge downstream, which has the same length and same spans but different deck width.
