ABAQUS Modeling and Investigation of Nuclear Central Cooling Tower Reinforced by CFRP

Abstract

Concrete is recognized as the most ideal material for construction of cooling towers. Because it is a relatively durable material to certain chemical environments, gases and high temperatures but, being a brittle material, concrete is damaged when subjected to tensile and flexural stresses. In addition, tensile and flexural stresses in high structures such as towers are caused by horizontal loads such as wind loads. Therefore, it is important to examine the materials used in such serious structures and the repair materials to be applied after construction. In this study, it is aimed to simulate a super-large reinforced concrete cooling tower using ABAQUS program as a sheet, by considering previous studies on the structure of cooling towers. In the models, the strain and stress behaviors against the wind load were investigated by reinforcing the middle zone of the tower by carbon fiber reinforced polymer (CFRP) sheets in different thicknesses.
