预应力混凝土构件在弯剪扭复合作用下剪扭承载力计算

Calculation of Shear-torsion Capacity of Prestressed Concrete Member under Combined Bending Shear and Torsion

本文对预应力混凝土构件在弯剪扭复合作用下的剪扭承载力，在试验研究和现有钢筋混凝土构件剪扭承载力设计方法的基础上，提出其当中心作用预应力时的计算公式。所建议的公式对８３个试件的剪扭承载力进行验算，符合程度较好．

Based on the experimental study and the available design methods of reinforced concrete member under shear and torsion, an equation for calculating the shear-torsion capacity of central prestressed concrete member under combined bending, shear and torsion is presented in the paper. The calculated resultS of 83 speciman are in agreement with the test results.
