后张预应力空心板试验研究及有限元分析

Static Test and Finite Element Analysis of Post-tensioned Hollow Slab

后张预应力空心板是预应力板发展的新方向。为了更好地了解后张预应力空心板的受力性能,对空心板进行了静载试验,并利用有限元软件对其进行了有限元分析,比较各相关数据,得到了在静载下的受力性能。分析表明,空心板具有令人满意的承载能力和正常工作能力。

Post-tensioned hollow slab is a new type of post-tensioned slabs.In order to investigate the load-carrying properties of post-tensioned hollow slab,static-load experiments are carried out.The finite element analysis is conducted by using finite element software in this paper.The relevant data are compared,and the load-carrying properties under the condition of static load are obtained.The analysis results indicate that both bearing capacity and normal working performance are satisfactory.
