摘要
为了对围护墙多功能减震结构(EWMVS)进行减震效果的试验研究,本文根据试验方案中的结构模型和动力参数在有限元分析软件SAP2000中建立了EWMVS的有限元模型,并进行基本特性对减震效果的影响分析,旨在研究EWMVS的减震原理及减震效果。研究结果表明,EWMVS体系的位移和加速度响应相对于抗震结构的降低幅度分别为43.41%、45.12%,说明EWMVS对减震有效,且子结构应尽量满布、频率比越接近1.0减震效果越好,最后,提出了围护墙多功能减震结构中减震装置性能参数的确定原则,设计中应根据实际结构的具体情况对EWMVS的各参数进行必要的优化。
Before the experimental study of the damped effect of enclosure wall multi-functional vibration-absorption structure,the finite element model is built in SAP2000 with the same parameters of testing program and the impact analysis of the fundamental properties to damped effect is processed to discuss the damped principium and damped effect of EWMVS.The findings indicate that the displacement and acceleration of EWMVS decreased 43.41%and 45.12% compared to the antiseismic structure which demonstrate the effectiveness of this structure.The substructure should fill the whole structure and the frequency ratio should be closed to 1.0.In the end,the setting principle of EWMVS parameters is proposed which should be optimized when designed in actual engineering.
