自复位防屈曲支撑框架结构混合试验研究
|
摘要
基于adapter单元构建了一套虚拟混合试验系统,利用混合试验方法对BRB型钢框架和SCBRB型钢框架进行了地震响应分析。本系统在计算机中利用两个有限元分析程序交互运算,实现混合试验过程,可以较为准确地模拟防屈曲支撑和自复位防屈曲支撑在地震作用下的受力行为。最后将混合试验结果与纯数值计算结果进行了对比,研究了防屈曲支撑和自复位防屈曲支撑对钢框架结构减震性能的影响。研究成果也验证了开展防屈曲支撑框架结构地震响应的物理混合试验的可行性,为后续混合试验在该领域的应用打下了基础。
A virtual hybrid simulation system based on adapter element is constructed in this paper.The seismic responses of buckling-restrained braces(BRBs) and Self-centering BRBs(SCBRBs) steel frames are analyzed with the hybrid simulation method.In this system,two finite element analysis programs are used to interact with each other in the computer to realize the hybridsimulation process,which can accurately simulate the mechanical behavior of BRBs and SCBRBs under earthquake.The hybrid simulation results are compared with the analyticalresults,and the effects of BRBs and SCBRBs on the seismic performance of steel frame structures are studied.The test results also verified the feasibility of carrying out the physical hybrid simulation of seismic response of BRB frame structures and laid a foundation for the application of the subsequent hybrid simulation in this field.
