摘要
根据钢纤维钢筋混凝土圆洞梁的受剪试验结果,分析和探讨了钢纤维对圆形腹洞梁抗剪性能的影响及受剪机理,提出了钢纤维钢筋混凝土圆洞梁的斜截面抗裂荷载和抗剪承载力的计算公式。并对这类梁的设计和构造措施提出若干建议。
According to the test results of ten steel fiber reinforeced concrete beams with circular openings and two reinforced concrete ones, the influence of steel fibre on the shear behaviour of reinforced concrete beams with open-ings is studied, and the formulas for calculating the cracking load and shear strength are presented. Some suggestions on the design method and construc-tion measures of the beams are also proposed.
