摘　　要：制作实验梁,设计、制作实验装置,制定加载方案并进行加载试验,验证推荐形式的抗扭预应力筋的可行性,指出配置抗扭预应力筋可以提高复合受扭梁的开裂扭矩和抗扭刚度,并推荐折线螺旋形配筋的预应力混凝土受扭梁的抗扭强度计算公式。Two beams are made based on literature; test installation are designed and made; loading scheme is also determined. Test data are recorded through the process of loading. Test data is analyzed and the feasibility of the proposed anti-torsion pre-stressed tendons form is validated; the fact that embedding such pre-stressed tendons can improve torsion crack moment and torsion rigidity is also pointed out; and a for- mula is proposed for calculating the anti-torsion strength of RC beams with anti-torsion pre-stressed ten- dons embedded in.
