本文通过对成吉思汗博物馆外壳的计算、分析,探讨折板式网壳的可行性及不规则折板网壳的空间作用效果。通过对计算结果的分析,在屋盖水平方向折板布置极其不规则的情况下,通过合理布置环线连接,屋盖空间整体作用非常明显,结构整体刚度远远大于单榀拱桁架或单片折板,周边落地折板网壳在满足建筑不规则外形的同时,同样可以保证网壳的完整性和刚度。对于大跨度整体作用结构,温差造成的温度变形和温度应力是工程中必须解决的问题,采用合理的结构布置能够有效地减少温差对下部结构的影响。
Through the calculation and analysis of the shell of the Genghis Khan museum, this paper discusses the feasibility of the folding plate reticulated shell and the spatial effect of the irregular folding reticulated shell. Through the analysis of the calculation results, under the situation that the folding plates are arranged irregularly in the horizontal direction of the roof, the overall effect of the roof space is very obvious through the rational arrangement of the loop connection. The overall rigidity of the structure is far greater than that of the single arch truss or the monolithic folding Plate, around the landing flap Reticulated to meet the irregular shape of the building at the same time, can also guarantee the integrity and stiffness of the reticulated shell. For the long-span integral structure, the temperature deformation and temperature stress caused by the temperature difference are the problems that must be solved in the project. The reasonable structure arrangement can effectively reduce the influence of the temperature difference on the lower structure.
