[摘要]大連國際會(huì)議中心是一個(gè)大跨空間鋼結(jié)構(gòu),其結(jié)構(gòu)形式復(fù)雜,規(guī)模大,屋蓋結(jié)構(gòu)總的平面投影覆蓋面積為25 097.2m2,最大跨度為94.572m。對(duì)該屋面結(jié)構(gòu)進(jìn)行了深入分析,得出了其在特征值屈曲、幾何非線性屈曲、彈塑性幾何非線性屈曲下的穩(wěn)定承載力,并對(duì)不同分析條件下的穩(wěn)定承載力進(jìn)行了比較、分析。

Abstract:Dalian International Conference Center is a large-span space steel structure with complex-structure and-large-scale. The total area coverage of roof is 25 097.2m2, and the maximum span is 94.572m. Through the analysis of the roof structure, the stability capacity under eigenvalue buckling, geometric nonlinear buckling, and geometrically nonlinear elastic-plastic buckling were obtained. The stability capacity under different conditions was analyzed and compared.
Keywords:roof stability; eigenvalue buckling; geometric nonlinear; elastic-plastic
