能力设计方法在双层高架桥梁抗震设计中的应用

共和新路高架工程是国内首座结合了道路高架桥与地铁高架桥的一体化双层高架结构,具有形式特殊、抗震危险性高的特点.以其为背景,介绍采用能力设计方法的抗震设计思路和具体应用步骤.通过对此设计方案进行的非线性时程地震反应分析和大比例模型拟动力试验,证实能力设计方法的可行性和有效性.

Application of Capacity Design Method to Seismic Design of Double-Deck Viaduct

The Gonghexin Road Viaduct is the first domestic double-deck viaduct structure integrating both roadway and subway utilization and is characteristic of special structural form and high level seismic vulnerability. By way of example of the Viaduct,the seismic design considerations based on the capacity design method and the specific application procedures of the method are introduced and the feasibility and effectiveness of the method are verified as well through the analysis of nonlinear time history seismi...
