B类规则连续梁桥抗震延性设计初探

Preliminary Search for the Anti-seismic Ductility Design of the Continuous Girder Bridge of Class-B Rules

对B类规则连续梁桥在E2地震作用抗震设计的主要流程进行了梳理,并以某高速公路跨线桥为背景,通过SAP2000有限元程序构建两跨连续梁桥抗震性能分析,通过分析E1地震和E2地震作用下的响应结果,对桥梁重要的抗震构件进行评估。

Combing through the main procedures of anti- seismic design of the continuous girder bridge of Class- B rules under the action of earthquake and taking the background of a certain expressway flyover,it provides an analysis of the anti- seismic performance of two- span continuous girder bridge built with SAP2000,moreover,it also gives an assessment of significant anti- seismic members of the bridge through the analysis of the responses of E1 and E2 earthquake actions.
