摘要
简述了增量动力分析(IDA)方法的基本原理,编制了IDA的计算程序,结合桥墩的抗震性能评估,研究了恢复力模型对评估结果的影响。
The fundamental of Incremental Dynamic Analysis (IDA) is introduced in this paper, and the seismic performance assessment of bridge piers is coded. How the restoring force models influence the result of performance assessment is studied.
