摘要:

论述了支座沉降对结构设计的影响,合理地选取了支座沉降的最不利工况; 采用SAP软件分析了新加坡植物园展览温室的拱壳杂交钢结构体系在各种工况作用下的结构内力,根据结构内力确定了结构主要构件的截面尺寸; 采用ANSYS软件进行了8种组合工况下的结构静力分析。结果表明:考虑支座沉降的组合工况作用下的结构应力与变形均满足要求,具有一定的安全性,支座沉降引起的附加应力与变形相对其他荷载而言较小,对该工程的影响不大; 支座沉降工况的选取可为类似工程提供参考。

Abstract:

The effect of arch settlement on structural design was discussed, and the worst arch support settlement load cases were selected. Structural internal force of arch-reticulated shell hybrid steel structure at Garden in Singapore under different cases was analyzed by using software SAP, then the section dimensions of main members of structures were determined according to the structural internal force. The static analysis of the structures were carried out by using software ANSYS under eight load combination cases. The results show that the stresses and deformations under combination cases considering support settlement can satisfy need, and the structure has certain safety. The additional stresses and deformations due to support settlement are more smaller than other loads, which have little effect to the project. The way to choose support settlement can be referred by similar projects.
