［摘要］密柱支撑低层钢结构工业化住宅体系为一种新型工业化住宅体系。通过对一个采用加强型高频焊接H型钢梁贯通式节点构造的足尺结构进行循环试验，揭示了该结构体系在水平地震作用下的抗侧力机制和破坏模式、抗震性能与恢复力特性，得出了其刚度、承载力、延性与耗能能力的变化规律，提出该类结构体系的设计建议。［关键词］密柱支撑；抗震性能；梁贯通式节点；工业化住宅中图分类号：TU391文献标识码：A文章编号：1002-848X(2012)06-0139-03Cyclic loading test on close-column supported low-rise industrialized steel building systemYang Jianxing(Zhejiang Construction Industry Research Institute, Baoye Group, Shaoxing 312000, China)Abstract: The close-column supported low-rise industrialized steel building system is a new kind of industrialized building system. One full-scale model test was carried out to investigate seismic performances of the system under lateral earthquake. The lateral seismic mechanisms, failure modes and hysteretic characteristics of the building system were evaluated. The variation of the stiffness, loading bearing ability, ductility and energy dissipation ability were explored. The stiffened beam-passed-through joint with high frequency welding H-typed steel beams was adopted. Some design suggestions were also recommended for the building system.Keywords: close-column support; seismic performance; beam-passed-through joint; industrialized building system作者简介：杨建行，硕士，高级工程师， Email：baoyeyjh@163.com参考文献［1］周晓红.模数协调与工业化住宅的整体化设计［J］. 住宅产业，2011 (6)：53-55.［2］周青. 分层装配式支撑钢结构体系抗震性能和设计方法研究［D］. 上海：同济大学, 2012.［3］GB 50011—2010建筑抗震设计规范［S］.北京:中国建筑工业出版社，2010.
