Serviceability of buildings is affected by excessive acceleration experienced at the top floors in wind storms that may cause discomfort to the occupants. To ensure functional performance of tall buildings it is important to keep the frequency of objectionable motion levels below the discomfort threshold. This paper addresses a new approach that facilitates mitigation of wind induced motion of ...

In the present paper we develop an approach to obtain sharp spectral asymptotics for Steklov type problems on planar domains with corners. Our main focus is two-dimensional sloshing problem, which a mixed Steklov—Neumann boundary value problem describing small vertical oscillations of ideal fluid in container or canal uniform cross-section. We prove two-term asymptotic formula eigenvalues. part...

Sloshing waves in moving tanks have been studied numerically, theoretically and experimentally in the past several decades. Most reported studies have been for tanks excited by forcing motion in a limited number of directions and with fixed excitation frequencies throughout the forcing. In the present study, a time-independent finite difference method is used to simulate fluid sloshing in the t...

We consider the problem of the active reduction of structural vibrations of a plane wing induced by the sloshing of large masses of fuel inside partly full tank. This study focuses on an experimental device composed of an aluminum rectangular plate equipped with piezoelectric patches at the clamped end and with a cylindrical tip-tank, more or less filled with liquid at the opposite free end. Th...

Trapped modes in the linearised water-wave problem are free oscillations of an unbounded fluid with a free surface that have finite energy. It is known that such modes may be supported by particular fixed structures, and also by certain freely-floating structures in which case there is, in general, a coupled motion of the fluid and structure; these two types of mode are referred to respectively...

The tank is one of the most important components in train which serves as a place to store fuel. However, so far has been component that gone unnoticed, even though there very issue consider, namely how fluid moves due movement while moving. free liquid called sloshing. Sloshing can be reduced by adding anti-sloshing baffles. So it necessary simulate sloshing taking into account value vehicle s...

Sloshing due to ground motion develops large pressure on the walls of water retaining tanks. This paper evaluates the efficacy of padded walls on the reduction of sloshing effects in rectangular water storage tanks subjected to ground motion. An analytical solution based on velocity potential function is provided to obtain the response of  rigid and padded wall tanks in terms of the wave elevat...

The stress at the support structure of clarification tank is large, which will have a certain impact on whole structure. typical concentration phenomenon cause structural damage and serious harm to steel itself. In order study influence bearing plate seismic response tank, this paper analyzes dynamic by setting different thickness plates connection between column body tank. Based displacement, ...

Vibration of a floating roof in cases tube and foam seals has been analyzed by ANSYS. Fluid-Structure Interaction (FSI) sloshing phenomenon have considered. Modal responses, time waves frequency spectrums the vibrations two sealing were evaluated during horizontal seismic excitation tank base. Then, effects main mechanical factors seal on vibration investigated. The amplitude case was considera...
