Abstract

In this study, fluid-structure interaction problem is investigated by solidity ratio approach. In the first case (Case I) steady flow conditions are defined by using air as fluid. The wind forces acting on the space lattice systems are determined by considering the solidity ratio dictated by ANSI/TIA-222-G (Steel Antenna Towers and Antenna Supporting Structures) technical specification. Stability of wind tower is analyzed using SAP 2000 software program. In the second case (Case II) unsteady flow conditions are evaluated by utilizing water waves acting on lattice marine structures. Models are occurred two groups as three space frame structures and three porous media models. Hydrodynamic wave forces are represented by the Stoke’s Second Order wave theory. Morison equation is employed to obtain lateral wave forces. The results of computational fluid dynamics are performed by using ANSYS-Fluent software. Solidity ratio is used to observe vortex effect that is based on turbulence around the structural members. The hydrodynamic forces acting on the marine structures are presented independent from configuration, depending on solidity ratio values.
