摘要
通过8根集中荷载作用下,配有500MPa钢筋的混凝土梁的受剪承载力破坏试验,分析了500MPa钢筋混凝土梁在使用阶段的受剪承载力,以及T形截面翼缘对裂缝宽度和受剪承载力的影响。同时对矩形梁与T形梁的受剪承载力进行了对比。试验结果表明:T形截面翼缘对斜裂缝的宽度有一定的影响,但影响不大;T形截面的抗剪承载力明显大于矩形截面。
The shear bearing capacity of concrete beam with HRB 500 bar and the impact of the T-section＇s flange at service stage on the width of crack and on the shear bearing capacity were analyzed according to the tests of 8 concrete beams with HRBS00 steel bar under concentrated load . The comparison of shear bearirg capacity between T-section beam and rectangular one was carried out. There is certain influence of T-section＇ flange on width of the diagonal crack, but it is not considerable and the shear bearing capacity of the T-section beam is larger than that of rectangular section one.
