摘　　要：通过对发生局部破坏的干煤棚网壳结构进行极限承载能力分析 ,采用短期荷载组合对受损网壳的极限承载能力进行核算 ,继而得出结构的极限破坏形式。结果表明 ,网壳结构具有较高的安全储备 ,是一种合理的空间结构。同时提出了一些改进壳体结构设计的建议 。This paper performs the ultimate bearing capacity analysis on a reticulated shell of dry coal shed that has some local damages to check the ultimate bearing capacity of the damaged reticulated shell with short term load, and gets the ultimate failure form that can still hold the short term load. The result indicates that safety factor of the reticulated shell structure is rather high and that the reticulated shell structure is a kind of rational space structure. Furthermore some advices to improve the design of the reticulated shell structure are put forward and can be helpful to designer.
