Abstract
Wind induced failure process of RC hyperbolic cooling towers (HCTs) considering material nonlinearity was investigated numerically. Following a detailed introduction and several numerical verifications on the material models of concrete and reinforcement and the layered shell element, the failure process, ultimate strength and failure mechanics of a tower under two load cases, with or without winter temperature, were discussed via the load–displacement curves, distribution and evolution of cracking, stress and internal forces. Loss of the load-carrying capacity is preceded by severe cracking of concrete in windward; and yielding of reinforcement in windward when winter temperature is not included.
