Wind-Structure Interaction Simulation Using Simplified Structural Models
In the field of engineering that takes into consideration the effects of air as a fluid, boundary wind tunnel simulations represent a reliable and good solution for the investigation of various problems. However, a rapidly growing field of technology and computational power, gives more and more possibilities and applicability for numerical simulations. Moreover, advances in the numerical fields give possibilities to a fully-coupled simulation of winds structure interaction. The procedure involves an approach in the time domain for the coupling of the two systems (fluid, and structure) as they heavily rely on each other. The current research focuses on a fully coupled Wind Structure Interaction. A simplified solution strategy, enables capturing of the dynamic effects of the wind, exerted on structures in form of Aerodynamic forces and base moments or reactions. The present paper outlined the proper choice and setup of the involved modules that are CFD, CSD and FSI. Simplifications and assumptions were made for the real models, taking care that an adequately and sufficiently complex modeling is used. The Python based implemented tool, allows for the tuning of structures to desirable frequencies according to its structural layout by adjusting its stiffness properties. The structural system is represented by a simplified formulation, that can present advantages due to its simplicity for an initial design. The outcomes of the concept will be presented on a tall building that undergoes the dynamic loading of the wind.
