The Possible Causes of Damage to Concrete Tanks, Numerical Experiment of Fluid-Structure-Soil Interaction

Abstract

Ground-supported open top circular concrete tanks are critical and strategic structures. There tanks are used in the commercial and industrial applications to store a variety of liquids as water or other products such as liquid chemicals and hazardous substance. Damages or collapse of containers may be due to the influence of surrounding aggressive environments or an earthquake. This paper provides numerical model on seismic response of fluid - structure - soil interaction. The article also will be described impact aggressive environment in terms of standards and its impact on the quality of the concrete tank.

Dynamic analysis of soil-structure interaction effects on NPP building using simplified and solid FE model of layered subsoil

“…The dynamic stiffening characteristics of the subsoil depend not only on the physical and mechanical properties of the soil, but also on the shape and depth of the base structure [5,10,[12][13][14][15][16][17][18][19]. Some authors consider the soil stiffness of rectangular foundation by the equivalent diameter of circular plate:…”

Experimental and numerical analysis of ceiling panel deflection

“…It was considered to find ways how to reconstruct the ceiling panels in the stable buildings and thus extend their service life [11][12]. The aim of the research was to monitor static characteristics, such as element deflection and crack formation while loading [13].…”

Determination of Pressure Coefficient for a High-Rise Building with Atypical Ground Plan

“…The wind effects vary in accordance with the shape or height of designed buildings. It depends also on the surroundings which alter with the city development [4]. The effects of the wind on a building are usually determined using the external pressure coefficient c pe .…”
