摘要
为了适应市场对大跨度楼盖结构的需要，在总结当前楼盖体系主要指标的基础上，提出一种新的“大跨度预应力空腹楼盖结构”体系。此结构不仅可满足跨度18m左右的建筑需要，且使楼盖结构层高度相对降低。并对这一结构进行了初步设计和内力分析，从而证实了其良好的空间工作性能，是一种具有广阔应用前景的新体系。
In demand of the architecture market for large span floor frame, this paper proposes a new kind of large span prestressed open - web floor frame system on the basis of summarizing and developing the current ones. This kind of system is not only suit for 18m span buildings, but also lowers the height of the floor frame system comparatively. The original design and internal force analysis of the frame in this paper show its satisfactory spatial operational perfomance and widly application prospect.
