CECS 160:2004和GB 50011—2010抗震设计若干问题对比分析

Comparison and Analysis of Seismic Design Specifications in the CECS 160: 2004 and the GB 50011—2010

抗震设计发展趋势是基于多目标的性态设计。为适应将来抗震设计理念,通过对《建筑工程抗震性态设计通则(试用)》(CECS 160:2004)及《建筑抗震设计规范》(GB 50011—2010)两部规范中设防水准、设防目标、地震作用计算、变形限值等方面对比分析,指出两部规范的异同点,并得出按照CECS 160:2004规范计算的结构总水平地震剪力标准值高于按照GB 50011—2010计算的结果,甲类建筑甚至高出一倍以上等结论,为从事工程抗震设计和工程抗震研究的人员提供一定的参考和借鉴。

The performance based seismic design is one of promising trends. To adapt the performance based seismic design concept, comparison and analysis of some specifications such as the fortification level, the forti- fication objective, seismic loading, the deflection limit value, in the CECS 160：2004 ＂General Rule for Per- formance-based Seismic Design of Buildings （trial）＂ and the GB 50011--2010 ＂Code for Seismic Design of Buildings＂ were conducted. The common points and difference were discussed. It was found that the total hor- izontal seismic shear calculated based on the CECS 160：2004 is higher than that of from the GB 50011-- 2010. It is more obvious for the Type One buildings. The objective of this study is to provide some references for designers and researchers in seismic engineering.
