苏州公安应急指挥中心办公大楼斜柱转换设计

Oblique column transfer design on office building of Suzhou Public Security Emergency Command Center

介绍了苏州公安应急指挥中心办公大楼斜柱转换设计。通过对斜柱转换与桁架转换的分析比较可知,斜柱转换具有上下层刚度变化小、受力直接、高效可靠、构造简单等特点。通过对斜柱转换层楼板应力分析可知,转换层楼板分担了一定的水平力,结构设计时应加以重视。另外,对于三跨托两柱的斜柱转换形式,通过合理的抗倒塌概念设计,可以实现预期的抗倒塌效果。

The oblique column transfer design of office building of Suzhou Public Security Emergency Command Center was introduced. Through the analysis and comparison of oblique column transfer and truss transfer, it can be seen that the oblique column transfer has characteristics such as small stiffness change of upper and lower layers, direct loading, high efficiency and reliable mechanism, and simple structure. Through the analysis of the floor stress of the oblique column transfer floor, it can be seen that the transfer floor shares a certain horizontal force, and it should be pay more attention in the structural design. In addition, for tbe oblique column transfer form of three spans supporting two columns, a reasonable collapse resistance concept can be adopted to achieve the expected collapse resistance effect.
