(同濟大學建筑設計研究院，上海 200092)［摘要］以北京奧運會乒乓球館鋼屋蓋這一預應力張拉結(jié)構體系為背景，首先介紹了靜、動力彈塑性分析的基本理論與分析方法，重點采用ANSYS軟件對這一結(jié)構體系進行了靜力彈塑性全過程分析以及彈塑性時程分析，并對結(jié)構塑性發(fā)展機制、力學性能以及抗震性能進行了詳細的研究，研究結(jié)果表明屋蓋結(jié)構具有良好的整體工作性能。［關鍵詞］預應力張拉結(jié)構；彈塑性；極限承載力；抗震性能Static and Dynamic Elasto-plastic Analysis of Steel Roof of Beijing Olympic Ping-pong GymnasiumDing Jiemin,Kang Xiaoju,He Zhijun(Architecture Design and Research Institute of Tongji University,Shanghai 200092,China)Abstract:Based on steel structure roof of Beijing Olympic Ping-pong Gymnasium, the basic theory and method of the static and dynamic elasto-plastic analysis are first introduced. Software ANSYS is applied to perform the static elasto-plastic analysis and elasto-plastic time-history analysis. And the plasticity development,the force performance,the seismic performance of the structure are studied. The study revealed that this roof structure has well whole working performance. The results are given to be used as reference for the design of this kind of structures.Keywords:pre-stressed string structure; elasto-plastic; ultimate bearing capacity; seismic performance參考文獻［1］丁潔民，張崢.張拉雜交結(jié)構的體育館建筑概念和優(yōu)化設計［J］.建筑結(jié)構，2008，38(9).［2］王勖成，邵敏.有限單元法基本原理和數(shù)值方法(第2版)［M］.北京：清華大學出版社，1997.［3］張汝清，詹先義.非線性有限元分析［M］.重慶：重慶大學出版社，1990.［4］丁潔民，何志軍，康曉菊. 2008奧運乒乓球館預應力鋼屋蓋非線性分析與研究［J］.同濟大學學報，2007，35(7).［5］丁潔民，康曉菊，何志軍. 北京奧運會乒乓球館的地震反應特征分析［C］//第二屆全國抗震加固改造技術學術交流會論文集.
