沈阳星摩尔购物广场亮窗钢结构由单层网壳及树形支承柱构成。单层网壳为复杂的空间曲面,平面尺寸长约285m,宽约200m。网壳边界较多,周边均与混凝土结构交接,温度作用对结构设计起控制作用。通过采用弹性支座,在温度影响最为不利的地方设置一道温度缝,不仅大大降低了温度作用下的支座反力,同时将支座位移也控制在合理范围内。弹性屈曲及弹塑性稳定分析表明,该网壳结构具有较高的屈曲荷载和稳定承载力。
Shenyang Star Mall shopping mall bright window steel structure by the single-layer reticulated shell and tree-shaped support column. Single-layer reticulated shell is a complex space surface, the plane size of about 285m, width of about 200m. There are many reticulated shells and the periphery is allotted to the concrete structure. The temperature effect on the structure design plays a controlling role. By adopting the elastic support, a temperature seam is set at the place where the temperature is most unfavorable, which not only greatly reduces the reaction force of the support under the temperature, but also controls the displacement of the support within a reasonable range. The elastic buckling and elastoplastic stability analysis show that the reticulated shell structure has high buckling load and stable bearing capacity.
