| 摘 要： | 根据25根预应力钢纤维混凝土无腹筋梁和20根预应力钢纤维混凝土箍筋梁斜截面受力试验研究，分析了箍筋、剪跨比、有效预压力、钢纤维体积率和长径比对预应力钢纤维混凝土梁斜截面抗裂度的影响规律. 通过理论推导，提出了预应力钢纤维混凝土梁的斜截面抗裂的计算公式。

| Abstract: | Based on the experimental study on the shear behaviors of forth-five prestressed steel fiber reinforced concrete beams, the effects of the stirrups, the shear-span to depth ratio, the effective precompressed force, the volume fraction and aspect ratio of steel fiber on the shear cracking strength of prestressed steel fiber reinforced concrete beams are analyzed. The theoretical model and the practical formulas for calculating the shear cracking strength of prestresseed steel fiber reinforced concrete beams are proposed. |

| Keywords: | steel fiber prestressed concrete beam shear cracking strength |
