ABAQUS modeling and investigation of nuclear central cooling tower reinforced by CFRP

Abstract

Concrete is recognized as the most ideal material forconstruction of cooling towers. Because it isa relatively durable material to certain chemical environments, gases and high temperatures but, being a brittle material, concrete is damagedwhen subjected to tensile and flexural stresses. Inaddition, tensile and flexural stresses in high structures such as towers arecaused by horizontal loads such as wind loads. Therefore, it is important toexamine the materials used in such serious structures and the repair materialsto be applied after construction. In this study, it is aimed to simulate asuper-large reinforced concrete cooling tower using ABAQUS program as a sheet, by considering previous studies on the structure ofcooling towers. In the models, the strain and stressbehaviors against the wind load were investigated by reinforcing the middlezone of the tower by carbon fiber reinforcedpolymer (CFRP) sheets in different thicknesses.
