摘要 同时考虑几何非线性与材料非线性,对单层球面网壳在地震作用下结构的最不利荷载进行分析。通过对场地卓越周期及地震波平台段持时的研究,建立结构动力响应与场地卓越周期及地震波平台段持时之间的关系,明确了何种条件下的荷载为结构最不利外荷载。 The most unfavorable earthquake excitations were investigated, in which geometric non - linearity and material non - linearity were all taken into account. According to the structural dynamic behaviors under different site conditions and seismic waves with different platforms, the relationships between the structural response and site predominant period, as well as platform of seismic wave were built up, by which the most unfavorable earthquake excitations of single- layer spherical shell were obtained.
