摘要
采用接近钢筋混凝土受弯构件实际受力情况的基本假定,对T形截面延性进行了分析,推导了较为精确的T形截面受弯构件截面延性系数的计算公式,研究了截面几何尺寸的变化对T形截面梁延性的影响,并与矩形截面进行了对比分析.研究结果可为工程设计人员参考应用.
Based on the basic assumption of the actual internal, forces of approaching to reinforced concrete beam, the calculating formulas of coefficient of reinforced concrete beam with T-shaped section were presented according to the analytical results. The paper also studied the influence of section geomatric size changes on ductility of T-shaped section, and compared then with those of rectangular section. The analytical results can be taken as references for engineering designers.
