通过利用非线性有限元软件ABAQUS建立模型,得到压扭构件的扭矩-扭率曲线以及混凝土、钢骨、钢筋的应力云图等。分析了6根钢骨混凝土构件和1根钢筋混凝土构件在压力和扭矩的共同作用下,轴压比、混凝土强度等级、钢骨配置、配筋率、含钢率等参数对构件抗扭刚度的影响。 Through the use of nonlinear finite element software ABAQUS to build the model, the torsion-torsional curve of the torsion member and the stress cloud of concrete, steel and steel are obtained. The effects of axial compression ratio, concrete strength grade, steel configuration, reinforcement ratio, steel content and other parameters on the torsional stiffness of the members were analyzed under the combined action of pressure and torque with six steel reinforced concrete members and one reinforced concrete member. influences.
