摘要
为了明确预应力筋的布置形式对UPC梁受弯性能的影响,设计了6片UPC梁,通过静载试验对比分析了两种不同预应力筋布置形式下UPC梁的受弯性能。研究表明,预应力筋的布置形式对UPC梁的极限承载力、极限应力增量、挠度和裂缝开展及分布均有影响;HRB500级高强钢筋作为非预应力筋可提高UPC梁的极限承载力和极限应力增量。
In order to figure out the effect of the layout of the prestressed steels on the bending property of UPC beams,six UPC beams are designed,and the effects of two different layouts of the prestressed steels on the bending property of UPC beams are compared and analyzed by the static load test.The test results show that the layout of the prestressed steels can impact the ultimate bearing capacity,ultimate stress increment,deflection and cracks of UPC beams.As non-prestressed steels,the HRB500 steels can improve the ultimate bearing capacity and ultimate stress increment of UPC beams.
