%X The interaction of water wave with arrays of combined cylinders with an solid interior column surrounded by a coaxial exterior column with perforated wall at a section in azimuthal direction is investigated theoretically. A semi-analytic linear solution has been acquired based on an eigenfunction expansion of velocity potential and a linear model between the pressure difference between two sides of a perforated wall and the fluid velocity inside it. Numerical experiments have been carried out to examine the influences on the wave force and wave run-up on the arrays of combined cylinders with perforated wall by the porous coefficient. The combined cylinder may reduce both the wave run-up and the wave loads on it through combination of certain parameters. It is found that the porous rate of the exterior wall have a significant influence on the wave run-up and wave loads. For certain parameter combinations, the porous combined cylinder may reduce the wave run-up or wave loads on it.
