【摘要】 通过对16根试验梁的试验结果,研究了钢纤维体积率、钢纤维类型、跨高比、纵筋配筋率等因素对钢筋钢纤维混凝土短梁变形性能的影响,结合有关规范,提出了与普通钢筋混凝土浅梁和钢筋钢纤维混凝土浅梁刚度计算方法相衔接的钢筋钢纤维混凝土短梁截面刚度的计算公式。更多还原

【Abstract】 Based on the results of experimentation on 16 testing beams, the effects of the volume fraction of steel fiber, the category of steel fiber, the ratio of longitudinal reinforcement and the span-depth ratio of the beams on the stiffness and load-deflection curves of steel fiber reinforced concrete short beams are discussed. Combining with the calculation method of the current criterions, the formula for calculating the stiffness of steel fiber reinforced concrete short beam is put forward, which is connected with those of normal steel fiber reinforced concrete beam.更多还原
