摘要:
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。
Abstract:
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.
