摘要:
为了研究高效预应力混凝土受弯构件的受力性能,对24根预应力混凝土梁进行了试验研究,分析了混凝土强度等级、预应力比率、配筋指数、钢绞线的延伸率等参数对试件裂缝、变形、受弯承载力和破坏形态的影响,并与规范(GB 50010—2002)进行了比较.研究结果表明, 受拉区仅配置预应力钢绞线的高效预应力混凝土受弯构件在正常使用阶段裂缝宽度和挠度可以控制,且钢绞线延伸率大小对其破坏形态有直接影响,并建议结构设计时应考虑钢绞线的延性对破坏形态的影响.
Abstract:
Twenty-four prestressed concrete beams were tested under static loading with constant amplitudes to investigate their flexural load-bearing capacity. Several factors are considered, such as grade of concrete strength, prestress ratio, reinforcement index and percentage elongation of steel strands. Effect of such factors on crack width, deformation flexural load-bearing capacity and failure mode are analyzed. The results are compared with the code(GB 50010—2002). It is concluded that crack width and deformation of high efficient prestressed concrete beams only with steel cable can still be under control, and the percentage elongation of steel strands has direct effect on the failure mode of the beams, and the effect of percentage elongation of steel strands on the failure mode should be considered during structure design.
