为研究型钢混凝土构件的复合受力性能,以扭弯比为研究参数,对5根型钢混凝土构件进行复合受力试验,详细描述了试件在不同扭弯比作用下的加载过程及破坏形态,得到型钢混凝土构件的弯型和扭型两种破坏形态。试验表明:扭弯比是影响型钢混凝土构件弯扭破坏形态的重要因素,适当的弯矩存在能显著提高型钢混凝土梁的抗扭强度。对试验数据分析得到型钢混凝土构件的弯扭相关方程。 In order to study the composite mechanical properties of SRC members, the torsional bending ratio was taken as the research parameter to test the composite SRFs of five SRC members. The loading process and failure mode of the SRC members under different twist ratios were described in detail. Bending steel structure and torsional deformation of the two forms. The test results show that the twist ratio is an important factor that affects the bending and torsion failure of steel reinforced concrete members. Proper bending moment can significantly increase the torsional strength of the steel reinforced concrete beam. Based on the experimental data, the bending and torsion equations of steel reinforced concrete members are obtained.
