摘　　要：通过对大跨空间结构屋盖进行计算分析,提出了对曲面复杂的大跨空间结构可以折线代替弧线,通过檩条找形而形成弧线,不仅施工方便,而且也更加经济。通过分析对比两端固定铰支座和一端固定另一端单向滑动支座这2种方式对下部主体结构框架柱水平推力的影响,尤其是在温差比较大的地区,其影响更加明显,最后提出了对大跨空间结构运营期间进行健康监测的必要性和意义。By calculating and analyzing the roof of large-span spatial structures,it is proposed that for complex curved large-span spatial structures,broken lines can replace curved lines and form curved lines through purlins.This not only facilitates construction but also makes it more economical.By analyzing and comparing the effects of two fixed hinge supports at both ends and one fixed unidirectional sliding support at the other end on the horizontal thrust of the lower main structure frame column,especially in areas with large temperature differences,this effect is more pronounced.Finally,the necessity and significance of conducting health monitoring during the operation of large-span spatial structures are proposed.The final result is expected to provide reference for similar situations.
