钢板深梁填充钢框架结构抗震性能试验及恢复力模型
|
摘要
钢板深梁填充钢框架作为一种新型耗能构件,可以实现宽范围的刚度渐变调幅。对2个钢板深梁填充钢框架试件进行低周反复荷载试验,得到钢板深梁填充钢框架的滞回曲线和骨架曲线。研究结果表明:2个试件的滞回曲线饱满且骨架曲线有塑性流动阶段。因此,钢板深梁可作为结构抗震的第1道防线,钢框架作为第2道防线。最后对试验数据进行回归分析,得到钢板深梁填充钢框架结构的恢复力模型,该模型可用于动力时程分析。
As a new energy component,the steel plate deep beam filled in a steel frame may realize the wide range of stiffness gradual attenuation.Through two plates deep beams filled in steel frame specimens of low cyclic loading experiment,it was obtained the steel plate beam filling the steel frame hysteresis curve and skeleton curve.The results of the study showed that their hysteresis curve was full and skeleton curves had plastic flow stage. Therefore,deep beams could be used as steel structure seismic first line of defense and steel frame as a second line of defence.Finally,using the test data a regression analysis of the steel beam filling deep steel frame specimens was done and the restoring force model was got,which could be used for dynamic time history analysis.
