摘要
主要研究基于推倒分析的普通减隔震支座连续梁桥的抗震性能评估方法。根据自适应的与质量成比例的推倒分析方法(AMPP)、MPA方法和时程分析方法(THA),评估了某常用减隔震支座连续梁桥的抗震性能。结果表明:AMPP方法可以成功地应用于常用减隔震支座桥梁的抗震性能评估,其对桥墩内力、支座位移和梁体位移的计算精度优于MPA方法。
Based on pushover analysis method,seismic performance of continuous bridges with common isolators are evaluated. Seismic performance of a bridge with common isolators is evaluated with adaptive mass proportional pushover analysis method( AMPP),modal pushover analysis( MPA) and time history analysis( THA). The results show that the AMPP is capable of evaluating seismic responses of isolated bridges. More accurate pier force,bearing displacement and girder displacement can be provided by AMPP method in comparison with MPA method.
