摘　　要：本文研究了钢纤维在矩形钢管混凝土梁中的应用。给出了钢纤维矩形钢管混凝土梁抗弯极限承载力的数值计算方法 ,并进行了钢纤维矩形钢管混凝土梁试验 ,通过掺入不同参数钢纤维梁和末掺入钢纤维梁的理论计算与试验分析 ,得出掺入钢纤维来提高梁的抗弯极限承载力是可行的。Theoretical and experimental studies on the behavior of rectangular steel hollow beams filled with steel-fibre-reinforced concrete are carried out in this pap er.A numerical model for calculating the ultimate bending resistance is describe d and experiments have been completed.Through comparison of theoretical analysis and experimental data of beams with various steel-fibre parameters and beams w ithout steel-fibre,the conclusion that the ultimate bending resistance can be i ncreased by rectangular steel hollow beams filled with steel-fibre-reinforced concrete is got.
