摘要
浦东国际机场T2航站楼主楼钢结构屋盖采用的Y形柱的稳定性能对整体结构的安全至关重要。通过对整体结构进行弹塑性大位移稳定性分析,针对Y形柱在不同荷载作用组合下的不同受力特点,采用考虑双折线材料模型、大位移几何非线性和初始几何缺陷的非线性计算方法,全面分析了竖向静力荷载下,X向和Y向水平地震作用下Y形柱的整体稳定性能。分析结果表明钢屋盖的Y形柱具有良好的稳定性能,是安全可靠的。
The stability of the Y-shape column is vital to the safety of the whole roof structure of Shanghai Pudong International Airport T2. Elasto-plastic large displacement stability analysis of the whole structure is carried out. According to different force feature of the Y-shape column under different load combinations, specific calculation methods are adopted to generally analyze the stability performance of the Y-shape column under vertical static load, X and Y-direction earthquake. It is shown that the stability performance of the Y-shape column is well and the structure is safe and reliable.
