在钢筋混凝土和高强混凝土超配筋纯扭构件中，由于配筋量过高使钢筋不能屈服，引起钢筋用量过多而产生材料的浪费。因此，在实际结构设计时，对构件截面尺寸不能采用过小，应加以限制，以控制这种超筋情况的发生。为此，本课题通过试验研究，对控制高强混凝土纯扭构件的截面限制条件，提出了具体的确定方法，供有关设计时参考。 In steel reinforced concrete and high-strength concrete super-reinforced pure torsion members, because of the high amount of reinforcement, the steel bars cannot yield, causing excessive amounts of steel bars and waste of materials. Therefore, in the actual design of the structure, the cross-sectional dimensions of the components cannot be too small and should be limited to control the occurrence of this super-relief situation. To this end, this project through experimental research, on the control of high-strength concrete pure torsion member cross-section constraints, put forward specific methods for reference when designing.
