Fluid-Structure Interaction in Civil Engineering
Edit
Fluid-structure interaction in civil engineering refers to mutual two-way coupled physical phenomena occurring between fluid flow and large-scale civil engineering structural components [1]. Fluid flow imposes time-varying pressure fields and shear stress loads upon structural surfaces; the resulting structural deformation, displacement and vibration responses conversely modify the local flow field distribution, flow separation pattern and vortex shedding characteristics of the surrounding fluid [2]. This coupling behaviour commonly emerges in civil infrastructures such as long-span bridges, high-rise buildings, offshore civil platforms, dams and hydraulic conduits under wind loading, wave loading or current loading conditions. Conceptually it excludes one-way static load calculation approaches, in which fluid pressure is applied onto structures without considering structural motion feedback modifying fluid flow states. It describes inherent coupled physical mechanisms rather than specific numerical analysis algorithms or engineering mitigation measures [3].
