新旧抗震规范下不同延性框架结构倒塌性能的研究

Study on the Anti-collapse Performance of Different Ductile Frame Structures Under Old And New Seismic Codes

建筑结构的抗震性能是抗震防灾系统中首要的环节,其中抗倒塌能力是抗震性能的表现指标,所以抗倒塌能力的强弱对结构的稳定性起到了决定性的作用。我国在2001版抗震规范的基础上,于2010年修订实施了新版抗震规范。该文采用目前较流行的弹塑性时程分析法,在基于SAP2000的弹塑性分析平台上,分别按照新旧抗震规范设计不同延性的框架结构,分析各结构在不同设防烈度下的抗倒塌能力。

The seismic performance of structures is a key link in seismic disaster prevention system, the ability to resist collapse is a indicator of the seismic performance, so the ability to resist collapse plays a crucial role in the stability of the structure. Based on the 2001 version of the seismic code, our country revised and implemented the new seismic code in 2010.This article used the current more popular elastic-plastic time history analysis method to analyze the collapse resistant capacity of some structures under different fortification intensity according to the old and new earthquake resistant design codes based on SAP2000 the elastic-plastic analysis platform.
