摘要
采用ANSYS有限元软件建立CFRP筋夹片式锚具数值有限元模型,通过分析计算结果,得出Tsai-Wu失效准则能够较好地模拟CFRP筋在复杂应力作用下的失效、荷载滑移的理论计算曲线基本能反映实际情况,锚杯外表面轴向应力和环向应力的计算值与实测值基本一致。
The numerical finite element of CFRP wedge anchor was built using ANSYS finite element software,by analyzing the calculated results,it can be concluded that Tsai-Wu failure criterion can simulate the failure of CFPR tendon at complex stresses well,the theoretical calculated curve of loadslip can reflect practice situation,and the calculated value of anchor rod external surface axial stress are in agreement with the measured value.
