| 摘 要： | 采用LANCZOS方法系统的计算了肋环型单层球面网壳结构的自振特性,分析了不同屋面荷载、不同失跨比、不同跨度、有无斜杆、不同支座条件和不同支座刚度下自振特性的规律,并利用了简谐响应分析的方法探讨了结构对频域上不同频率激励荷载的敏感程度。

| Abstract: | The free vibration characteristic of Schwedler single-layer spherical reticulated shells is analyzed taking into account the influence of many kinds of factors such as the span,the ratio of rise to span,the roof load,the size of grid,the condition of supports and so on,by use the LSNCZOS mothed.Then,differernt sensitivity of it to various inpulses in frequency shells is studied by applying harmonic lods. |
