摘要:
提出了层单元方法,将楼板视为剪切弯曲深梁,用二次位移函数和一次转角函数描述楼面运动。同时建立了平面非规则房屋隔震结构动力反应的计算模型,用反应谱方法和时程分析方法计算分析了U型和L型底部弱层非规则布置隔震结构的局部变形的基本动力性能。
Abstract:
The storey element model for irregular isolated structure is suggested in this paper.In the model the floors are considered as resisting bending-shear beams,and the floor movements are described with quadratic displacement function and primary angle function.The dynamic responses of isolated irregular buildings(U and L) with consideration of soft-bottom are analysed by response spectral method and time-history method.
