摘要

摘要: 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。

Abstract: In order to research the mechanic behavior of steel encased concrete members subjected to combined force.Experiments were conducted on five SRC beams with various ratios of torque to bending moment Loading process and failure modes of different specimen were described.Two failure modes(failure with torsional feature and failure with flexural feature) were obtained after analysis of the experiment.Tests and analysis results indicate that ratio of torque to bending moment is the important factor affects the failure mode,the ultimate torque moment can increase to some extent under a suitable bending moment.A flexure-torsion-correlation equation in three-phrase expression form of the SRC members is put forward.
- steel-encased concrete /
- ratio of torque to bending moment /
- failure with torsional feature /
- failure with flexural feature /
- flexure-torsion correlation equation
