Coupling OpenFAST with X-SEA
In the analysis and design of offshore wind turbine support structure, engineers need a solution for the coupled analysis of wind turbine and hydrodynamic loads on structures.
Fully coupled analysis of offshore wind turbine structure can be carried out using a high performance graphical input of OpenFAST and X-SEA.
The peak acceleration from the response spectrum is applied as a lateral force distributed along the structure. The seismic static coefficients are usually obtained from the seismic “zone”, which is corresponding to a level of seismic acceleration. X-SEA programs can perform static analysis using the load case of response spectrum.
Pushover Analysis the fiber-based finite elements
Pushover analysis is a nonlinear static procedure to estimate seismic structural deformations and commonly used to evaluate the seismic capacity of existing structures. It can also be useful for performance-based design of new structure that rely on ductility or redundancies to resist earthquake forces.
A fiber element model is thought to capture more accurate response effects than plastic hinge model. Geometrical and material properties are the only required ones as input. Geometrical and Material nonlinearity effects are taken into account.
Time History Analysis
The method of linear time history analysis provides an actual solution of the dynamic equation of motion. Time history analysis is a more accurate and computationally intensive method than response spectrum analysis.
