| 摘 要： | 根据超高层隔震结构等大高宽比隔震结构体系地震反应分析的单质点、双质点和三质点剪切型简化计算模型,对大高宽比隔震结构隔震层特性参数进行了研究,得出了隔震层水平刚度、最大设计位移和隔震支座压应力与界限荷载、压应力的关系.采用振型分解反应谱法,通过对地震反应分析预测简化计算方法的研究,提出大高宽比隔震结构的层间剪切力、层间变形以及层间最大位移反应等预测计算方法,以及多质点体系隔震层和上部结构的加速度反应分布计算理论式等.

| Abstract: | Based on the single-mass,2-mass,and 3mass shear computation models presented in this paper to analyze the earthquake response for large aspect-ratio isolated structure such as high-rise building,its isolated layer characteristic parameters were studied.The relationship of horizontal stiffness and maximum design displacement of isolated layer to the bound tension and compression stress of isolator was obtained.Simplified calculation models of earthquake response analysis were studied using decomposition response spectrum method.The calculation models of the layers shear,deformations, and maximum layers displacement of such structure were given,and the calculation theoretical formula of acceleration response and isolated layers of multi-mass isolated system were presented,also. |
