大跨度超长非对称储煤棚网壳结构分析

On analysis of large-span and super-long asymmetric coal storage shed reticulated shell structure

某电厂全封闭大型储煤棚采用了三心圆柱面网壳结构与端部网架结构的组合形式,通过用MST空间网格结构分析与设计软件对该结构进行计算分析,对结构的受力特点、动力特性等有了充分的了解,为以后进一步的优化设计提供了重要的依据和保证,同时,也为今后类似工程提供一些有用的工程经验。

The paper adopts the composite form with the three-centered circular cylindrical lattice shell structure and the end grid structure of the fully-dosed large-scale coal storage shed of some power plant, undertakes the calculation analysis of the structure by using MST space grid structure and the design software, has the full understanding of the stressed features and the dynamic characteristics of the structure, so as to provide the important reference and the insurance for the further optimization design, and to provide the useful engineering experience for similar projects in future.
