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.
