Contact Nonlinear Numerical Simulation of Steel and Concrete in Wind Turbine Foundation

Abstract:

Effective simulation and analysis about wind turbine foundation simplified model experiment were conducted by using general finite element analysis (FEA) program ANSYS. Nonlinear finite element model with surface-to-surface contact pair was built to study the strain distribution of the steel interface and slip between steel and concrete. Relevant strain and spreading length curves under the load of every class were obtained. The numerical simulation results were in good agreement with the experimental results. And proper parameters of bond-slip relationship for steel and concrete in wind turbine foundation were confirmed. The finite element model established and analysis results can provide a theoretical reference for later research, and have significant value for optimal design of wind turbine foundation.
