钢筋钢纤维高强砼梁正截面承载力的简化计算方法

The simple calculation procedure about cross-sectionbearing power of reinforcement steel-fibre beam high-strength concrete

在试验的基础上,通过对局部钢筋钢纤维高强砼梁的正截面受力性能进行分析,合理地对梁正截面的受力进行简化,从而推导出了局部钢筋钢纤维高强砼梁的正截面承载力计算公式,并指出此公式适用于普通钢筋钢纤维高强砼梁的正截面承载力的计算。经验证,公式的计算结果与实际受力情况相符。

This paper is on the basis of experiment, through studing the performance of load about the cross-section of 'part reinforcement steel-fibre high-strength concrete beam', educe the calculation formulas about cross-section bearing power of beam of part reinforcement steel-fibre high-strength concrete from the studing, and point out:the formulas fit the commonly 'reinforcement steel-fibre high-strength concrete beam' too. Through testing, the calculation results of the formulas is correspond with the actual force.
