某科技馆结构设计

Structure design of a science & technology museum

简要介绍了某科技馆项目的地基基础设计及结构的整体布置,并对其旋转坡道、悬挑屋面、斜柱等几处设计难点进行了介绍。对大跨度混凝土梁施加预应力,以控制挠度、裂缝。将旋转坡道与主体结构结合,增强了结构的整体性。屋面设置悬挑钢梁实现了悬挑屋面。通过预应力梁及钢骨梁,有效抵抗斜柱产生的水平拉力。

The foundation design and the structural overall arrangement of a science & technology museum were introduced briefly. Structural design of the revolving ramp,the cantilever beam and the inclined column were described in detail. Pre-stress technology was used to reduce the crack width and the deflection of the concrete beam. The revolving ramp was connected to the main structure. The cantilever steel beam was used in the roof structure. Pre-stressed concrete beam and SRC beam were used to resist the horizontal load induced by the inclined column.
