| Abstract: | By using the software ANSYS's nonlinear model,numerical calculations and analyses were carried out to simulate the full process of experiment of five RC flat plates with opening strengthen by CFRP.Through the finite element analysis,the regularity was investigated of the stress variation of reinforcement and CFRP as well as the developmental process of deformations and cracks of strengthened plates.A comparison was made between the results of FEA and experiment and the results of FEA agree well with the experimental values.This indicates that the nonlinear finite element analysis can provide a considerably good estimate of the mechanical performances of strengthen plates under pressure. |
