大柱网带平托板无粘结预应力无梁楼盖结构在福建会堂大型多层地下车库中的应用与研究

APPLICATION STUDY OF UNBONDED PRESTRESSED FALT SLAB STRUCTURE WITH DROP PANEL FOR FUJIAN HALL’S DOUBLE-STOREY BASEMENT GARAGE

本文结合福建会堂工程结构设计实践 ,介绍了带平托板预应力无梁楼盖的结构设计方法。工程应用表明 ,大型多层地下车库采用预应力无梁楼盖结构 ,与常规结构相比 ,可以降低地下室层高 ,减少基坑开挖深度和土方开挖量 ,降低围护结构造价 ,改善结构使用功能、方便、快捷施工、有明显的综合经济效益和社会效益。

Combined with Fujian Hall's structural design practice,unbonded prestressed flat slab with drop panel design procedure is introduced in this paper.The practice show that compared with common structure,unbonded prestressed flat slab with drop panel structure has advantages in terms of descend storey height,lessen excavation calculative depth et..
