【摘要】 在钢筋混凝土中 ,一般会出现超筋情况。由于超配筋构件是脆性破坏而且引起材料的浪费 ,因此 ,在实际设计中应对截面条件加以限制以控制超筋梁的使用。本文通过变角空间桁架理论分析 ,对钢筋混凝土的截面限制条件提出了具体的确定方法 ,可供工程设计人员参考更多还原

【Abstract】 In pure torsion reinforced concrete members,over-reinforcement usually happens.The failure is brittle failure,and the surplus bar is wasted.So,in the engineering design,the minimum section is used to control the over-reinforcement.By using the space truss theory with variable inclination,this paper puts forward the method to determine the minimum section.It can be used as reference for the engineering design.更多还原
