矩形钢管腹板开孔耗能支撑框架结构抗震性能研究

Jianzhu Gangjiegou Jinzhan
钢框架中心支撑结构是一种双重抗侧力结构体系，为避免水平荷载作用下中心支撑斜杆发生失稳，提出了矩形钢管腹板开孔耗能支撑，其与钢框架采用高强螺栓连接，进而形成耗能支撑框架结构，耗能支撑发生破坏后易于替换。耗能支撑的耗能板件采用对称开孔与S形开孔两种形式，利用ABAQUS有限元软件，分析了耗能腹板厚度、长度、开孔间距等参数对耗能支撑以及支撑框架滞回性能的影响。研究结果表明：两种开孔形式的耗能支撑框架结构的支撑斜杆均未发生失稳，结构滞回曲线饱满，无捏缩现象 ...

新型连接方式内嵌墙板钢框架拟静力试验研究

为了研究基于新型连接方式下内嵌墙板与钢框架结构的地震协同工作性能和破坏机理，对新型连接方式内嵌墙板钢框架、传统L形卡件连接内嵌墙板钢框架及纯钢框架等3种工况进行了拟静力试验，对比分析了3个试件的破坏模式、滞回曲线、骨架曲线和刚度退化曲线等抗震性能指标。结果表明：内嵌墙板能够提高钢框架的极限承载力、变形能力和刚度，传统L形卡件连接墙板钢框架的抗震承载力是纯框架抗震承载力的1.34倍，新型连接方式墙板钢框架的抗震承载力是传统节点框架抗震承载力的1.42倍。当加载位移为12 mm（层间位移角为1/133）时 ...
