屈曲约束耗能支撑在拉、压两种受力状态下都能达到屈服,是一种集抗侧力和耗能为一体的耗能减震构件。结合学校加固工程特点和支撑受力性能,应用屈曲约束耗能支撑在某平面严重不规则的教学楼中进行加固设计,通过反应谱以及非线性时程分析方法,比较研究采用支撑加固前后教学楼相关信息。结果显示,小震作用下支撑可很好地调整原有结构抗扭和抗侧刚度,大震作用下支撑能有效消耗地震能量,提高结构承载力,加固效果明显。
Buckling constrained energy dissipation can yield under the two kinds of stress state of tension and compression, which is a kind of energy-dissipative shock-absorbing component that integrates the lateral resistance and energy dissipation. Combined with the characteristics of school reinforcement project and the supporting force performance, the buckling restrained energy dissipation support was used to reinforce the design in a serious and irregular school building. Through the response spectrum and nonlinear time history analysis method, Related Information. The results show that the support under minor earthquakes can adjust the torsional stiffness and lateral stiffness of the original structure well, and the support can effectively dissipate the seismic energy and improve the bearing capacity of the structure under the action of large earthquake. The reinforcement effect is obvious.
