摘要 为研究矩形型钢混凝土复合受扭构件的抗扭性能,以轴压比、配筋率、混凝土强度、型钢尺寸为影响因素,通过ABAQUS对6根构件进行有限元分析,发现合理增大构件的轴压比能够显著提高型钢混凝土构件开裂前的抗扭性能;提高混凝土的强度能够提高构件的开裂扭矩,但对构件开裂后的抗扭性能影响极小;增加构件的配筋率会使构件开裂后的抗扭刚度显著提高;合理增大含钢率能够显著提高构件的开裂扭矩与开裂后的抗扭刚度。 To study the torsional performance of rectangular SRC composite torsion components,the finite element analyses of 6 components are carried out by ABAQUS with the influence factors of axial compression ratio,reinforcement ratio,concrete strength and steel size.,and it is found that reasonable increase of axial compression ratio can remarkably improve the torsion resistance of SRC members before cracking. Improving the strength of concrete can increase the cracking torque of the component,but it has little effect on the torsion resistance of the component after cracking. Increasing the reinforcement ratio of the members can increase the torsional stiffness of the members after cracking. Reasonable increase of steel ratio can significantly improve the cracking torque and the torsional stiffness of the components after cracking.
