| Abstract: | Simulation and analysis about trim size simplified model of wind turbine foundation were conducted by using general finite element analysis（FEA） program ANSYS.Surface-to-surface contact pair was built to simulate the contact function between steel and concrete.The bond-slip property between steel and concrete was studied.Load transfer mechanism and strain distribution of the models were analysed.The numerical simulation results were in good agreement with the experimental results.According to this,the finite element model established and analysis results can provide a theoretical reference for later research,and can be used for practical analysis in engineering. |
