摘要/Abstract

摘要： 本文基于钢纤维钢筋混凝土梁正截面构件大量试验,讨论钢纤维混凝土梁增强机理,分析几种应力增强计算公式的合理性,通过试验数据的统计对比,提出一种较为合理的计算钢纤维增强所产生的等效均布拉应力的公式。

Abstract: Based on a large number of experiments on the ultimate flexural strength of steel fibre reinforced concrete beams (SFRCB),the reinforcing mechanism of flexural strength of SFRCB and the rationality of several strength-calculating formulas are discussed in this paper.By the analysis of the experimental data,an ideal formula is proposed.

Key words: steel fibre reinforced concrete, flexural strength, bond stress, con-crete tensile strength
