摘要
本文通过普通钢筋混凝土框架、耗能支撑钢筋混凝土框架结构1/8比例模型的地震模拟振动台对比试验,研究两类框架结构在地震作用下的破坏形态和动力特征,揭示了耗能支撑钢筋混凝土框架结构良好的抗震性能;对试验模型进行了弹塑性时程分析,理论分析和试验结果符合较好;结合扬州电厂二期主厂房框排架结构,研究了其纵向框架结构采用耗能支撑体系时结构的抗震性能,为该类结构型式的工程应用提供依据
wo reinforced concrete frame models,one with energy-dissipation bracings and the other without bracing,have been tested on shaking table for comparison.The failure modes and dynamic characteristics of these two kinds of frame structures under earthquake excitations are studied.The test and non-linear time history dynamic analysis show the superior aseismic performance of the frame with energy-dissipation bracings.The non-linear time history dynamic analysis of the main frame structure of Yangzhou Power Plant shows that the frame with energy-dissipation bracings has better aseismic behavior than the frame with common bracings and can be proposed for practical use.
