通过对4根预应力筋不同布置形式和非预应力筋不同等级的梁进行静载试验,对比分析了不同预应力筋布置形式和不同非预应力筋等级对UPC梁受弯性能的影响。研究表明:UPC梁的极限承载力、极限应力增量、挠度和裂缝开展均受到预应力筋的布置形式的影响;非预应力筋强度等级的提高可以使UPC梁的承载力和极限应力增量有所提高。 Through the static load test of four different prestressed tendons and non-prestressed tendons, the effects of different prestressed tendons and different non-prestressed tendons on the flexural behavior of UPC beams were analyzed. The research shows that the ultimate bearing capacity, ultimate stress increment, deflection and crack initiation of UPC beams are affected by the arrangement of prestressing tendons. The increase of strength of non-prestressed tendons can increase the bearing capacity and ultimate stress increment of UPC beams has seen an increase.
