| Abstract: | 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 formula is proposed for calculating the anti-torsion strength of RC beams with anti-torsion pre-stressed... |
