多层大跨度装配式混合型空间钢网格盒式结构的工程应用

Engineering Application of Multilayer Large Span Assembled Hybrid Spatial Steel Grid Box Structure

本文介绍了一种新型的钢网格盒式结构-装配式混合型空间钢网格盒式结构,已申请相关发明专利,对其产生和发展做了简单介绍。针对此种新型结构,以某实际工程为例,采用SATWE程序对结构进行多遇地震作用下的计算,从周期比、位移角和位移比、承载力之比对结构抗震性能进行评估。分析结果表明,该新型盒式结构整体稳定性和抗侧刚度均较好,能够满足设计要求。

This paper introduces a new type of steel grid box structure-assembled hybrid spatial steel grid box structure, which has been applied for patent of related inventions, and has made a brief introduction to its emer-gence and development. According to this model, based on a practical project as an example, to calculate the structure under the action of multiple earthquakes by SATWE program, and the seismic performance of the struc-ture is evaluated by cycle ratio, displacement angle and displacement ratio, and the ratio of the carrying capacity. The analysis results show that the overall stability and anti-lateral stiffness of the new box structure are better, which can meet the design requirements.
