摘要
现有规范中没有明确地将拉压杆间夹角与腹板的配筋率、腹板钢筋的屈服强度和混凝土的极限抗压强度等因素联系起来。通过推导拉压杆夹角的取值范围和分析拉压杆夹角范围与腹板配筋率、腹板钢筋屈服强度和混凝土极限抗压强度等因素之间的关系,可为相关研究提供参考。
Existing criterions did not contact the strut-and-tie angle with the ratio of reinforcement of web plate, yield strength of reinforcing steel bar in web plate, compressive ultimate strength of concrete and other factors expressly. Deducing the span of strut-and-tie angle and analyzing the relationship during span of strut-and-tie angle, the ratio of reinforcement of web plate, yield strength of reinforcing steel bar in web plate, compressive ultimate strength of concrete and other factors can provide references for correlative research.
