某双曲抛物面钢网壳屋盖可靠性分析

Reliability Analysis on the Steel Roof of a Hyperbolic Paraboloid Latticed Shell

采用ＳＡＰ５结构分析程序，对３种不同边界约束假定下的某不规则四边形双曲抛物面钢网壳屋盖分别进行内力计算分析．结合实际工程的静载试验，对比理论计算与实测挠度分析。

Using SAP5 structure programming and considering different boundary restraint conditions, an analysis of the internal forces on the steel roof of the hyperbolic paraboloid latticed shell is proposed. With the experimental investigation of a practical steel roof the comparison between measurement and calculation of the displacements shows that the calculating result as the boundary displacements are replaced by test data is reasonable and the roof design is satisfactory.
