［摘要］密柱支撐低層鋼結構工業(yè)化住宅體系為一種新型工業(yè)化住宅體系。通過對一個采用加強型高頻焊接H型鋼梁貫通式節(jié)點構造的足尺結構進行循環(huán)試驗，揭示了該結構體系在水平地震作用下的抗側力機制和破壞模式、抗震性能與恢復力特性，得出了其剛度、承載力、延性與耗能能力的變化規(guī)律，提出該類結構體系的設計建議。［關鍵詞］密柱支撐；抗震性能；梁貫通式節(jié)點；工業(yè)化住宅中圖分類號：TU391文獻標識碼：A文章編號：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作者簡介：楊建行，碩士，高級工程師， Email：baoyeyjh@163.com參考文獻［1］周曉紅.模數(shù)協(xié)調與工業(yè)化住宅的整體化設計［J］. 住宅產(chǎn)業(yè)，2011 (6)：53-55.［2］周青. 分層裝配式支撐鋼結構體系抗震性能和設計方法研究［D］. 上海：同濟大學, 2012.［3］GB 50011—2010建筑抗震設計規(guī)范［S］.北京:中國建筑工業(yè)出版社，2010.
