矩形截面钢筋混凝土拉扭构件的极限强度

Ultimate Strength of R. C. Tension-Torsion Members with Rectangular Section

本文依据８根拉扭构件和３根作为对比的纯扭构件的试验结果，按变角空间桁架模型推导出拉扭构件极限强度的计算公式。公式合理地考虑了轴拉力对拉扭构件极限强度的影响作用。概念明确，计算简便。

Based on the test results of 8 tension-torsion members and pure torsion members,formulas for calculating the ultimate strength of tension- torsion members are derived according to the theory of space truss with variable angle.The effect of axial tension on the ultimate strength has reasonably taken into consideration. The suggested formulas have a clear concept and are easy to apply.
