摘要
介绍装配整体式空间钢网格正交斜放盒式结构体系在某实际工程中的应用,并与普通钢框架结构体系进行对比,分析了两种结构体系的周期、位移比、层间位移角、梁设计弯矩、楼面线弹性挠度和经济性能。结果表明,这种新型结构体系在力学性能和经济性能方面均优于普通钢框架结构体系,能够满足多层大跨度工业建筑的相关要求,为今后该结构体系在大跨度结构设计中的应用提供参考。
Orthogonal and diagnal c.assette structural system of assembled overall spatial steel grid was introduced in the application of a practical project. The. normal steel frame structural system and the new system were compared of the aspects of the period, displacement ratio, story drift angle, designed bending moment of the beam, floor elastic deflection and economic performance. The results show that the new structural system has better mechanical properties and economy performance compared with the normal steel frame structural system. The new system can fulfill relevant requirements of multi-storey large-span industrial buildings, which provides reference fi)r the application of the orthogonal and diagnal cassette structural system in the large-span structural design in the future.
