大开间短肢剪力墙结构抗震性能研究
|
摘要
对一栋12层一户一开间一进深大开间短肢剪力墙结构的1/10比例模型,采用不同加速度峰值的3种地震波作为激励,进行了模拟地震振动台试验研究,得到了模型结构的自振频率及加速度和位移等反应结果,并对模型结构的开裂部位、裂缝发展和破坏状态进行了观察分析。试验结果表明:在多遇地震阶段,结构未发生明显破坏;在罕遇地震阶段,连梁首先发生开裂,其后部分墙体出现破坏,但结构的整体性能良好。采用有限元软件ABAQUS对该模型结构进行了弹塑性地震反应分析,分析结果与试验结果吻合较好。研究表明,大开间短肢剪力墙结构具有良好的抗震性能,适合在7度抗震设防地区推广使用。最后,对该结构体系的设计方法提出了若干建议。
Following the prototype of a 12-storey residential building,a 1/10 scaled model of large bay short limb shear wall(SLSW) structure was designed and constructed.The seismic behavior of the tested structure was experimentally evaluated with three input earthquake waves of different peak values on the shaking table.The natural frequncy,responses of acceleration and displacement of the tested structure were obtained as well as the cracking postions,the development of cracks and the damage of the structure were observed.According to the experimental results,under the frequent earthquakes,damage was unobvious;under the rare earthquakes,the linking beams cracked firstly,and then damage developed in some shear walls,however,the whole performance of the structure was still good.Furthermore,the elasto-plastic seismic response analysis of the tested structure were performed using ABAQUS program,and the analytical results were consistent with the experimental results.The research indicates that the large bay building has good seismic performance,and is suitable for being used in the regions with the seismic fortification intensity of 7.0.Finally,some suggestions are given for the design of such structure system.
