【摘要】 针对索穹顶结构在施工过程中不可避免的会产生预应力分布差异的现象,提出合理的方法即几何非线性方法对索穹顶结构进行静力分析,并编制相应的计算程序,判断索穹顶结构在正常使用状态下结构是否有效。此程序为施工预应力是否需要调试提供判别的依据。更多还原

【Abstract】 For cable dome structure in the construction process will produce difference phenomenon prestress inevitably,geometric nonlinearity is proposed to analysis the force of cable dome structure,which method is reasonable.Structure in actual construction under normal service condition whether failure is judged,and the calculation program is worked out.This conclusion provides a judgment for whether need prestress debugging.更多还原
