%X 收集了国内外学者所做的281根高强混凝土有腹筋梁剪切破坏的试验数据，建立了高强混凝土有腹筋梁剪切破坏的数据库。将数据库中所有梁的试验结果与中国《混凝土结构设计规范》（GB 50010―2010）、美国混凝土结构设计规范ACI 318？？14中的公式以及Zsutty公式所预测的结果进行比较，研究各公式对于高强混凝土梁的适用性，再将GB 50010―2010公式中的系数进行修正，得到一个新的公式。结果表明：Zsutty公式的预测结果最精确，美国ACI 318？？14规范中公式的预测结果最为保守；新公式较原规范公式更加适用于高强混凝土有腹筋梁。<br>The experimental data of shear failure of 281 high-strength concrete beams with web reinforcement were collected, and a database of shear failure of high-strength concrete with web reinforcement was established. The results of all the beams in the database were compared with those predicted by GB 50010―2010, ACI 318-14 and Zsutty equation. The applicability of each formula to high strength concrete beam was studied. Then, the formula in GB 50010―2010 was modified to get a proposed formula. The results show that the prediction results of the Zsutty equation are the most accurate, and the prediction results of the formula in ACI 318-14 are the most conservative. The proposed formula is more suitable for high strength concrete beams with web reinforcement compared to the formula in GB 50010―2010
