摘　　要：板锥网壳结构是一种受力性能合理,技术经济效益良好的新型空间结构形式。首先采用子空间迭代法对板锥网壳结构的自振特性及其影响因素进行了系统分析研究,并与普通双层网壳结构进行比较,然后分别采用振型分解反应谱法和时程分析法对板锥网壳结构进行了地震响应分析,得出了可应用于工程实践的重要结论。Plate-cone reticulated shell is a new type of space structures with good mechanical behavior and technical economy. The dynamic characteristics of plate-cone reticulated shell and the influences of some parameters on them are analyzed thoroughly by use of the sub-space iteration method, and compared with those of double-layer reticulated shell. The seismic responses of plate-cone reticulated shell are also analyzed with mode decomposition response spectrum method and time-history analysis method, and the computation results of both kinds of methods are contrasted. Some important conclusions for plate-cone reticulated shell are obtained for practical design.
