摘要
通过预应力空腹楼盖1／2缩尺模型在使用荷载和承载能力极限荷载下的试验观测，探讨了空腹楼盖在加载过程中的空间工作性能，包括刚度、裂缝、破坏形式、破坏荷载和预应力筋的应力状态。试验结果表明：该结构体系具有良好的工作性能，即使用荷载下满足设计要求、破坏形式为塑性破坏、结构的徐变具有收敛性等。
In this paper, a test on the prestressed open - web floor frame system model which was made to 1 /2 scale is introduced. Under the service and ultimate loads, the three - dimension structure behaviors of the system, including rigid, crack, failure form, failure load and the stresses in the prestressed reinforcements are discussed in detail. The test shows that, this kind of system works well and can meet the demands of the design under service loads. Besides, its failure is plastic failure and its creep is convergent with time
