Finite Element Analysis and Bearing Capacity Research of the New GFRP Strengthening Frame Members Based Modified Behavior

摘要整理

Based on the research of the new kind of glass fiber reinforced plastics based modified unsaturated polyester (MUPR-FRP). This paper presents the result of the numerical evaluation of bearing behavior of the MUPR-FRP strengthening frame members. The MUPR-FRP strengthening members were modeled using the nonlinear finite element software ANSYS and the load deflection behavior and ultimate capacity were evaluated numerically. For the FE model, members were modeled using Tsai-Wu with tension cut-off failure criterion. The numerical results and the bearing capacity research indicated that the stress of new MUPR-FRP strengthening frame members was less than the load bearing strength and the deformation could satisfy some requirements in use.
