(1 中国建筑标准设计研究院， 北京 100048; 2 (株)堀江建築工学研究所， 东京）[摘要] 以北京地区某高层办公建筑为例，分别依据中、日两国结构设计规范及惯用设计手法，采用不同的弹塑性分析方法，对结构进行设计验证与抗震性能评价。日本地震反应分析过程采用非线性静力推覆分析与使用等效楼层质点系模型的时程分析相结合的方法。中国则采用大型通用有限元软件，以构件为基本单位，进行地震反应解析。对比中、日结论差异，对我国现有结构设计方法和通用设计手段进行反思，分析日本抗震设计方法中值得我国结构设计学习的先进方面。[关键词] 中日抗震设计对比; 高层建筑; 推覆分析; 弹塑性分析中图分类号：TU973.3+1 文献标识码：A 文章编号：1002-848X(2013)S2-0377-06作者简介：刘晗，硕士，Email：liuhan1128@gmail.com。Comparative analysis of atall building anti-seismic design basing on Chinese and Japanese analytical methodsLiu Han1, Deng Xuan1, Zhang Linzhen1, Sakuta Joji2(1 China Institute of Building Standard Design & Research, Beijing 100082, China; 2 Horie Engineering and Architectural Research Institute, Tokyo, Japan)Abstract: This paper takes a typical tall office building in Beijing as an example and evaluates the building seismic resistance capacity by using the Chinese and Japanese codes and methods respectively. The Japanese nonlinear analysis method combines the nonlinear push-over analysis and the dynamic analysis together. In China the general FEM analysis software with element-level model is used for dynamic nonlinear analysis. By comparing the Chinese and Japanese results, exam the Chinese structural analysis method and draw on advanced experience from Japan.Keywords: Chinese and Japanese anti-seismic designs comparison; tall building; push-over analysis; nonlinear analysis
