摘要
襄阳东津站站房为线上式高架站房,屋盖结构跨度大、局部有起伏曲面。为此,以屈曲模态作为初始缺陷和以重力荷载代表值下的位移分布作为初始缺陷进行全过程弹塑性稳定分析。结果表明,屋盖结构具有较高的极限承载力,且屋盖结构极限承载力对初始缺陷不敏感。
The Xiangyang Dongjin railway station is a station above the railway line.There are some characteristics in the roof structure,such as long span and partial undulating curved surface. The initial geometric imperfection of buckling mode and displacement distribution under the representative value of gravity load were adopted to perform the detailed elasto-plastic time-history stability analysis.The results showed that the roof structure could maintain higher ultimate bearing capacity,and it was not sensitive to the initial imperfection.
