摘要
通过对钢纤维钢筋混凝土梁的斜截面抗剪试验分析,研究了在不同纤维掺量、配箍率的情况下,钢纤维对混凝土梁斜截面裂缝的形成和扩展、极限荷载的影响,试验结果表明钢纤维能够显著地提高梁的极限荷载。
The test results of several shear-critical fiber reinforced concrete beams with varying stirrup content and fraction of steel fibers were presented in this paper. The influence of steel fiber on the cracking and ultimate strength was analyzed. It was found that steel fiber provided significant improvements in ultimate strength.
