20 m跨径后张预应力混凝土空心板梁变形的试验研究

Test Study of Prestressed Concrete Hollow Slab Beamby Post-Tensioning with Twenty Meter Span

介绍了二十米跨径预应力混凝土空心板梁的荷载试验结果，并对该梁的裂缝开展及挠度发展等变形行为进行了分析研究。此外，通过该梁的非线性计算结果与实测结果的分析对比，对预应力混凝土空心板梁的非线性破坏规律进行了有益探索。

In this paper, the experimental results on a prestressed concrete hollow slab with twenty meter span were reported. The deformation behaviors of the hollow slab beam were analyzed. Besides, through the analysis and contrast of the theoretical results and measured ones, the nonlinear deformation and failure behaviors on the hollow slab beam were discussed.
