摘要
通过采用大跨度预应力空心平板楼盖技术的框架核心筒结构设计实例,总结其设计方法和设计经验,并与普通梁板楼盖结构进行比较。实践表明,大跨度预应力空心平板楼盖技术在高层框架核心筒结构设计中应用是可行的,计算中可将空心平板简化成正交梁系。
A design example of adopting prestressed concrete hollow-plate floor with large span in frame-core wall system is introduced, and the design method and experience are summarized, The comparison with the common beam-slab system for the same project is presented, The practice shows that the technique can be used in the high-rise frame-core wall structures and the hollow-plate floor can be calculated with the method of equivalent beam.
