摘　　要：研究了单层网壳结构的多维地震反应特点。建立了结构的三维有限元模型以及多维地震激励作用下的动力分析方法。在此基础上以某凯威特型网壳为工程背景,研究了结构的多维地震响应的特点并比较了结构单维地震响应和多维地震响应的差异。考察了不同类型地震激励和不同结构阻尼对结构地震响应的影响。The performance assessment of a reticulated shell subjected to three-dimensional seismic excitations is actively carried out in this study.The finite element model is constructed and analytical method is also developed.A Kiewitt shell is taken as an example to examine the nodal deformation and internal forces subjected to 2D and 3D earthquake.The structural responses subjected to different seismic excitations and damping levels are also analyzed to examine the effects of inputting excitation and damping ratios on the structural dynamic performance.
