11-05: Structural Integrity Of Hyperbolic Cooling Towers In Seismic Zones

Abstract: Concrete cooling towers in seismic zones that have been exposed to corrosion causing conditions are susceptible to deterioration over a period of time. When repair to such towers are considered, large areas of concrete will need to be removed from the structures. This may impair the structural integrity to withstand dynamic loading due to earthquakes. The paper will provide an approach in developing some guidelines for repairs to minimize the risk of structural distress in a seismic event that occurs without warning.
