摘要
针对弹性分析时钢筋混凝土边梁扭矩过大,抗扭设计困难的问题,提出以钢筋混凝土梁开裂扭矩为界限扭矩,考虑塑性内力重分布的抗扭设计方法,并与美国混凝土规范ACI318M-05中最大设计扭矩值Tu进行对比,验证该方法的可靠性。
Based on the problem of excessive torsion and hard to design when elastic analysis on reinforced concrete boundary beam,put forward the design method of taking the cracking torque as the limit torque and taking the redistribution of plastic internal forces into account,and compare with the maximum design torsion value Tu of Building Code Requirements for Structural Concrete(ACI 318M-05)to verify the reliability of this method.
