【摘要】 采用大质量法对不同场地条件、不同矢跨比的70 m跨单层球壳和100 m跨双层球壳进行多点输入下的水平地震作用时程分析,通过结构最大位移概率密度函数来分析判断与归纳了球壳结构的倒塌破坏模式。更多还原

【Abstract】 Adopting large mass method and considering different site conditions and rise-span ratios,this paper made time-history analysis of the 70 m single layer and 100 m double layer spherical shells under the horizontal seismic loads,probability density functions of the structural maximum displacement probability have been used to judge and summarize the failure modes of spherical shells.更多还原
