摘要
对钢框架-灌浆轻钢剪力墙结构足尺试件进行了水平低周往复加载试验,研究了灌浆轻钢剪力墙与钢框架的耦合效应,分析了结构的破坏模式、受力特征和耗能机理,得到了结构的承载能力、抗侧刚度、延性及耗能能力等.通过与纯钢框架及冷弯薄壁型钢灌浆墙体结构的试验结果对比,发现灌浆轻钢剪力墙通过自攻螺钉采用内嵌的方式与钢框架连接,二者具有良好的协同工作性能,框剪结构的抗剪承载力和抗侧刚度分别是钢框与墙体对应值之和的1.50倍和1.64倍,结构延性系数达5.42,抗震性能优良,研究结果可为该类结构的设计研究提供科学基础.
Abstract
The horizontal low cyclic reversed loading test of full-scale steel frame-grouting light steel shear wall structure is carried out,the coupling effect of grouting light steel shear wall and steel frame is studied,and the failure mode,stress characteristics and energy dissipation mechanism of the structure are analyzed.The bearing capacity,lateral stiffness,ductility and energy dissipation capacity of the structure are obtained.Compared with the test results of pure steel frame and cold-formed thin-walled steel grouting wall,it is found that the grouting light steel shear wall is connected with steel frame by self-tapping screw,and the two have good cooperative performance.The shear bearing capacity and lateral stiffness of frame-shear structure are 1.50 times and 1.64 times of the sum of steel frame and wall respectively,the ductility coefficient of structure is 5.42,and the seismic performance is excellent.The research results can provide a scientific basis for the design and research of this kind of structures.
