چکیده مقاله:
Sloshing due to ground motion develops large pressure on the walls of water retaining tanks. Thispaper evaluates the efficacy of padded walls on the reduction of sloshing effects in rectangular waterstorage tanks subjected to ground motion. An analytical solution based on velocity potential function isprovided to obtain the response of rigid and padded wall tanks in terms of wave elevation, maximumpressure on the tank wall and FFT spectrum of pressure on the water surface. In the proposed method,the boundary condition on the tank wall is kinetic representing pressure distribution on the tank wallsagainst the usual methods with kinematic boundary condition only. The fluid is assumed to be inviscid,incompressible, and irrotational. Tanks with and without padded walls are evaluated under differenttypes of ground motions classified as near source and far-field records. The results show noteworthyeffect of the padded wall on reduction of above-mentioned sloshing responses.
