H型型钢混凝土压扭构件极限扭矩的计算初探

Calculation of Limit Torques of H-Type SRC Pressure-Torsion Members

以叠加原理为基础,对H型型钢混凝土受扭构件极限扭矩的计算公式进行了推导,探讨了H型型钢混凝土受扭构件在压扭作用下极限扭矩的计算,并对不同轴压比作用下构件的受力性能进行了分析,经公式计算值与试验值的比较,得出构件极限扭矩计算值与试验值基本吻合,验证了公式的正确性.

Based on the superposition principle,the calculation formula of limit torques of H-type SRC prsssure-torsion members is derived and the calculation of the limit torque of the H-type SRC pressure-torsion member also discussed in this paper.Meanwhile it analyses the mechanical behavior of the SRC member in different axial compression ratios.By means of comparing the formula calculation with the experimental value,the analytical results basically agree with those of the experiments.
