摘要
跳层空腹网架在利用网架的空腹部分做楼层使用时,网架的上、下弦杆均与楼板浇注成为一个整体,以往对跳层空腹网架结构的力学性能分析均未考虑楼板刚度的影响.本文对普通型跳层空腹网架结构在竖向荷载作用下考虑楼板不同刚度和不考虑楼板刚度进行了比较分析,揭示了楼板对空腹网架受力性能的影响规律.本文的结论可为跳层空腹网架结构的工程设计提供参考.
The upper and lower chords of vierendeel grids and the floor slabs are usually casted into an integration when the open-web parts of the grids are used for an architectural room. The influences of the floor slabs stiffness are usually neglected in past researches on interval vierendeel grid structures. The comparision are presented between considering floor slab different stiffness and neglecteing floor slab stiffness in the regular vierendeel grid structures under vertical loads in this paper. The influences regularity of the floor slab stiffness on the properties of vierendeel grid structures is revealed. The results of the paper can offer renferences to design this kind of interval grid structures.
