摘要:
开孔式双钢管约束屈曲支撑是一种性能良好的耗能减震构件,且适用于网壳结构.利用ANSYS有限元分析软件对开孔式双钢管约束屈曲支撑进行了拉压循环荷载作用下的滞回性能的模拟分析.为了验证这种新型约束屈曲支撑替换网壳结构部分杆件后的减震效果,设计制作了球面网壳结构模型,进行了开孔式双钢管约束屈曲支撑替换网壳杆件的振动台试验.在替换杆件不多的情况下,主要测点的动力响应有所减小,说明新型约束屈曲支撑在网壳结构中的减震策略有效、可行
Abstract:
The perforating double-steel tube buckling-restrained braces(BRBs)is an energy damping device, which can be suitable for space structure as a novel device of good performance. Based on the ANSYS software, the hysteretic curve of the perforating double-steel tube buckling-restrained brace through the simulation of the cyclic-loading test is obtained. In order to test the vibration reduction effect of the reticulated Shell with several elements replaced by the perforating double steel tube the vibration test of a reticulated Shell model with several elements replaced by the BRBs was carried out on the shaking table. The result shows that the seismic response of shell with Buckling Restrained Braces decrease, and that this study is valuable for further research and practical application for the vibration control of reticulated shell
