摘要
根据钢筋钢纤维混凝土牛腿的试验结果,研究了钢纤维体积率对牛腿正截面开裂弯矩的影响,将梁的正截面开裂弯矩计算方法运用于牛腿的正截面开裂计算中,给出了钢筋钢纤维混凝土牛腿正截面开裂弯矩的计算公式.该计算方法与试验结果符合较好,且计算简便,实用性强,并与钢筋混凝土牛腿的计算公式相衔接,可供实际工程设计时参考应用.
The effect of steel fiber volume ratio on the cracking,resistance moments of a corbel normal section was taken into consideration according to the results tested. Application of the normal section's cracking,resistance moment calculation of a beam to the same calculation for the corbel has led to a formula for calculating the normal section cracking,resistance moments of a steel fiber reinforced concrete corbel. The results calculated from this method well conform to those of testing. Its profits are easy calculation,practical use,having the same calculation conception as the general reinforced concrete corbel. The method would be possible to be applied for similar construction designs.
