印度尼西亚城市高架桥梁抗震设计

Seismic Design of Urban Elevated Bridges in Indonesia

摘要:

随着我国设计行业走向全世界，需要在当地设计要求下进行各类桥梁设计。印度尼西亚作为地震带上的国家，其桥梁抗震设计尤为重要，而印尼桥梁抗震设计基于AASHTO规范体系，并采用当地的地震参数和作用组合进行补充。因此，在进行雅加达内二环项目中的主线高架桥梁设计时，首先对其设防标准、验算方法和内容进行了梳理，然后采用Sap2000有限元分析软件对该桥进行了地震响应分析和抗震性能验算。结果表明：所设计的主线高架桥梁能满足当地规范提出的抗震要求，可为类似工程设计提供参考。

Abstract:

As the design industry of China expands globally, it is necessary to carry out various bridge designs under local design requirements. As a country located on the earthquake belt, the seismic design of bridges in Indonesia is particularly important. The seismic design of bridges in Indonesia is based on the AASHTO specification system, and is supplemented with the local seismic parameters and action combinations. Therefore, in the design of the elevated bridges in the main line in the Jakarta Inner Ring II Project, firstly, the fortification standards, verification methods and contents are sorted out, and then the seismic response analysis and seismic performance verification of the bridge are carried out by using Sap2000 finite element analysis software. The results indicate that the designed elevated bridge in the main line can meet the seismic requirements proposed in the local codes, providing a reference for the design of similar projects.
