This paper describes the development of an efficient numerical model, namely scaled boundary finite-element method (SBFEM) for linear waves interaction with cylindrical structures of arbitrary shapes. The two-dimensional Helmholtz equation is firstly

Wave interaction with a porous cylindrical breakwater is studied analytically by linear potential wave theory. The breakwater is assumed to have a thin skin, is bottom-mounted and surface-piercing. The porosity of the breakwater is uniform vertically

A suspension bridge over a river is generally supported on a structure mounted on large concrete piers placed on the river bottom near the two banks. Because of its massive size the piers are built by pouring concrete at site in a floating position.

An offshore platform that is efficiently designed to reduce the wave excitation forces and increase the separated-flow damping could qualify as a platform operating even near its resonance. Such design could make this concept cost-effective, as well

The motivation of this work came from the design and construction of a new suspension bridge in the Tacoma Narrows next to an existing bridge. The new bridge like the old one was designed to be supported on two large concrete piers at its two ends. T

The newly constructed Tacoma Narrows Bridge Piers represent large concrete floating caissons during their construction. For designing their mooring system the current force applied on the caissons in the Narrows must be known. The flow field around t
