摘要
首先通过对比结构在施加预应力前后变形情况,得出预应力在钢结构双层幕墙中的重要性,再分别用幕墙规范和抗震规范对结构进行侧向稳定分析,说明不同规范的巨大差异所造成的影响。
Firstly, the importance of prestress in double steel structure facade is got by comparing the deformation before and after prestress. Secondly, structural lateral stability is analysed after imposing the seismic load calculated from technical code for glass curtain wall engineering and code for seismic design of building. It explaines the huge impact made by different code.
