摘要
为了研究角钢桁架型钢混凝土梁在扭矩作用下的受力性能,进行了6根角钢桁架型钢混凝土梁和1根钢筋混凝土对照梁纯扭试验。通过试验研究,揭示了角钢桁架型钢混凝土梁在纯扭作用下的受力机理与破坏形态,分析了角钢桁架型钢混凝土梁受扭性能的影响因素。试验结果表明,角钢桁架型钢混凝土梁比普通钢筋混凝土梁的抗扭性能有很大的提高,大体上随着腹杆体积配钢率的提高而增大,其中增加斜腹杆试件的抗扭性能最好。
In order to study the capacity of angle steel reinforced concrete beam （ASRCB） under torque, 6 angle steel reinforced concrete beams and 1 reinforced concrete beam were carried out. Through the experiment research reveals the working mechanism and faihrre modes of ASRCB under pure torsion, the factors of effect on the capacity were also analyzed. Experiment results the torsion properties of ASRCB than RCB has been greatly improved, and as the steel reinforcement ratio per unit volume increased with the increase .among them the torsion properties of mechanism with increasing inclined abdomen pole is best.
