（西安建筑科技大学土木工程学院， 西安 710055）［摘要］对一榀缩尺比为1∶3的单跨双层半刚性框架-纵横密肋加劲防屈曲低屈服点钢板剪力墙结构进行了低周往复加载试验。从滞回性能、承载力、刚度、耗能能力、结构延性及破坏模式等方面对纵横加劲的防屈曲性能及低屈服点钢内嵌板的工作性能进行评价。研究结果表明：纵横密肋有效延缓了内嵌板的屈曲，提高了结构的延性和极限承载力；低屈服点钢内嵌板与半刚性框架具有良好的协同工作性能，内嵌板采用低屈服点钢可有效提高结构的延性和耗能性能；整体结构具有理想的破坏模式，试件破坏主要由内嵌板的区格内局部屈曲、撕裂和框架塑性铰的形成控制。［关键词］防屈曲剪力墙;纵横加劲;低屈服点钢;抗震性能;低周往复加载试验中图分类号：TU398 文献标识码：A 文章编号：1002-848X(2015)10-0005-05Experimental research on seismic performance of vertical and horizontal stiffened buckling-restrained low yield point steel plate shear wallGuo Zhao, Hao Jiping, Fang Chen, Yuan Changlu(School of Civil Engineering, Xi′an University of Architecture and Technology, Xi′an 710055, China)Abstract:The experiment was carried out under low cyclic loading on a 1∶3 scale two-story and one-bay semi-rigid connection frame with vertical and horizontal stiffened buckling-restrained shear wall with low yield point steel plate. Buckling-restrained performance of the vertical and horizontal stiffeners and the overall performance of semi-rigid connection frame with low yield point steel infill plate were evaluated according to the analysis of hysteretic behavior，bearing capacity，energy dissipation，ductility and failure mode. The analysis results show that vertical and horizontal stiffeners perform well in restraining the buckling of the infill plate and improve the ductility and ultimate bearing capacity of the structure，the failure mode of the steel plate is local buckling. There is good overall performance between low yield point steel infill plate and the semi-rigid frame. The infill plate of the low yield point steel can improve the ductility and energy dissipation of the structure. The structure has desirable failure mode, the specimen destruction is mainhy controlled by the infill plate local buckling, tearing and the plastic hinge of the frame.Keywords:buckling-restrained shear wall; vertical and horizontal stiffened; low yield point steel; seismic performance; low cyclic loading experiment* 国家自然科学基金项目（51178381），国家自然科学基金青年项目（51408461），陕西省教育厅科研计划项目（14K1395）。作者作者：郭昭，硕士研究生，Email：charmerone@126.com。参考文献［1］郭彦林，董全利.钢板剪力墙的发展与研究现状［J］. 钢结构，2005,20(1):1-6.［2］郭彦林，陈国栋，缪友武.加劲钢板剪力墙弹性抗剪屈曲性能研究［J］. 工程力学,2006,23(2):84-91.［3］郭彦林，周明，董全利.防屈曲钢板剪力墙弹塑性抗剪极限承载力与滞回性能研究［J］. 工程力学，2009,26(2):108-114.［4］郭彦林，董全利，周明.防屈曲钢板剪力墙滞回性能理论与试验研究［J］. 建筑结构学报，2009,30(1):31-39.［5］于金光，郝际平.半刚性连接钢框架-非加劲钢板剪力墙结构性能研究［J］. 土木工程学报，2012，45(8):75-82.［6］郝际平，郭宏超，解琦，等.半刚性连接钢框架-剪力墙结构抗震性能试验研究［J］. 建筑结构学报，2011,32(2):33-40.［7］GB/T 2281—2010金属材料 拉伸试验 第1部分：室温试验方法［S］. 北京：中国标准出版社，2010.［8］GB/T 2975—1998 钢及钢产品力学性能试验取样位置及式样制备［S］. 北京：中国标准出版社，1999.［9］JGJ 101—96 建筑抗震试验方法规程［S］. 北京：中国建筑工业出版社，1997.
