配筋强度对预应力混凝土构件抗扭强度的影响

The Effect of Reinforcement Strength on Torsional Strength of Prestressed Concrete Beams

在修正斜压场理论的基础上,模拟一系列预应力混凝土试验构件。研究了纵筋和箍筋的配筋强度对构件抗扭强度的影响,并根据模拟试验结果,绘出了配筋强度指标对抗扭强度的影响曲线。

Based on the modified diagonal compression field theory,a series of prestressed concrete beams were simulated.The effect of longitudinal and transverse reinforcement strength on torsional strength was researched.According to the simulative results,the effective curves of reinforcement strength index to sorsional strength are depicted.
