The article studies for the future of prestressed steel beam constructionerror on the structural effects of the accumulation of information.
本文对此进行研究，为今后的预应力钢束施工误差对结构影响积累资料。

The movable roof favors the flexural structural system that is less sensitive to boundary conditions and can be adaptive to the large deformation and constructionerror.
活动屋盖应采用整体刚度较小、对边界条件不敏感的柔性结构，对安装误差与结构变形具有较大的适应能力；
