摘要
通过轴拉力较大条件下钢筋混凝土构件的试验,研究了从受力到破坏整个过程中拉扭、拉弯扭构件变形和裂缝的发展。根据桁架模型对其开裂后的抗扭刚度提出简单实用的计算式。计算结果与试验对比,符合较好。
Through the experiment under tension and torsion ,and tension,bending and torsion,the deformation and crack behavior of reinforced concrete beams are studied. Based on a space truss model,a simple formula for torsional stiffness after cracking is derived theoretically. The calculated results show a good agreement with the test ones.
