【摘要】 框架柱间设置支撑可以提高框架刚度,在水平地震作用下能够有效控制结构层间位移。但传统钢支撑容易受压发生屈曲破坏,影响耗能能力。提出了一种端部带滑块的单向受拉支撑模型,并对3榀带钢滑块的单向受拉支撑钢框架在低周反复荷载作用下进行试验研究。在试验基础上通过有限元分析,比较了新型单向受力支撑与普通单向受拉支撑在地震水平荷载作用下的耗能能力。表明新型单向受力支撑可以有效控制水平地震作用下的层间位移和框架的耗能能力,并具有体积小、安装方便的特点。更多还原

【Abstract】 In this paper,a new type braced frame structure with a slip device is presented.Three specimens which have different angle of the brace are designed for low cyclic reversed lateral loading tests to verify the energy-dissipation capacity of the new type braced frame structure.The seismic energy dissipated ability between the new and normal type braced frame structures are compared based on the experimental and calculated results.The test result shows that the new type brace with the angle of 45 degree possesses excellent energy dissipation capacity.更多还原
