（1中国建筑设计研究院 北京 100044 2 浙江大学建筑设计研究院 杭州 310012）[摘要] 钢框架梁柱节点一直是钢结构设计和研究中的重点。本文从高层钢框架中常见的箱型柱工字梁节点的破坏机理入手，推导了极限承载力的公式，并与有限元的模型分析结果进行了比较。[关键词] 梁柱节点;箱型柱;有限元分析;设计研究中图分类号：TU973.1+3 文献标识码: A 文章编号：1002-848X(2013)S1-0422-03作者简介：王浩，高级工程师，Email：wanghao@cadg.cn。Research on ultimate resistance of i-beam- box-column jointsWanghao1 ，Shenjiepan2(1 China Architecture Design & Research Group, Beijing 100044, China; 2 Architectural Design & Research Institute of Zhejiang University, Hangzhou 310012, China)Abstract: The beam-column joint in the steel framework is the key in steel structure design and research. This paper is discussing the failure mechanism of I-beam-Box-column joint ,and also have formula derivation. Some finite elements are built in this paper and compared with the result of the formula.Keywords: framework;joint;Box-column;finite element analysis; design study
