(1 中国建筑标准设计研究院,北京 100044; 2 山东大学,济南 250061)[摘要]针对现行建筑抗震设计规范在多高层钢结构房屋梁柱刚性连接设计方法上的技术矛盾和存在的问题,进一步推出能够满足结构抗震安全要求的解决方案,其中包括几种耐震型连接节点作法和详细说明,并附以算例和对比,推荐了既有良好抗震性能又较符合我国国情的新型钢结构梁柱节点形式。[关键词]梁柱刚性连接节点;加强型连接;削弱型连接;强弱综合型连接New types and computing method for endure anti-seismic beam-column rigid joints of high-rise steel structuresLiu Qixiang1, Chen Youfan1, Chen Qinglai2(1 China Institute of Building Standard Design & Research,Beijing 100044,China;2 Shandong University,Jinan 250061,China)Abstract:For contradictions in current Code for Seismic Design of Building about steel beam-column rigid joint design,the submissive practical scheme is proceeded which can satisfy the safety demand of anti-seismic, including several kind of endure earthquake joint design with detailed explain and contrasted examples. The computation results show that the recommend new joint pattern which have good anti-seismic behavior and better accord with the condition of our country for steel structure design.Keywords:steel frame; column-beam rigidity joints; strengthen type connection; weaken type connection; strengthen & weaken synthetical type connection作者简介:刘其祥,教授级高工,Email:lqx3960@sina.com。参考文献[1]刘其祥,陈幼,陈青来.现行建筑抗震设计规范多高层钢结构梁柱刚性连接设计方法的技术矛盾[J].建筑结构,2010,40(6).[2]GB50011—2001建筑抗震设计规范[S]. 2008年版.北京:中国建筑工业出版社, 2008.[3]JCJ99—98高层民用建筑钢结构技术规范[S].北京:中国建筑工业出版社,1998.[4]GB50017—2003钢结构设计规范[S].北京:中国建筑工业出版社, 2003.[5]杨尉彪,高小旺,等.高层建筑钢结构梁柱节点试验研究[J].建筑结构,2001,31(8).
