Through simultaneously considering geometric non-linear and material non-linear,the dynamic responses of single-layer spherical latticed shells subjected to harmonic loads and step loads were researched respectively,and the most unfavorable dynamic loads of the structure were analyzed.
同时考虑了几何非线性与材料非线性,分别对简谐荷载、阶跃荷载作用下的单层球面网壳进行了最不利动荷载分析:通过变换简谐荷载的频率和阶跃荷载的持时,明确了结构动力响应与其自振特性及荷载频谱特性之间的关系,确定了何种条件下的荷载为结构最不利动荷载。
