Analysis and Design of Strengthened Hyperbolic Cooling Tower by Using PDS Module in ANSYS

Abstract

In consideration of the uncertain factors, a hyperbolic cooling tower with initial geometrical imperfections is studied by the PDS module in ANSYS. Contrastive analysis is made on stress, internal force, displacement and failure probability of cooling tower shell. It is indicated that the value of Mx and Ty is sensitive to the initial geometrical imperfections, and the failure of shell in imperfections increase in large. On top of this, the non-local cooling tower shell strengthened with FRP is found to solve the insufficient capacity, which is proved to be feasible. Lastly, the reliability analysis and design of tower shell strengthened with FRP are also carried out. It is proved that the probability design of strengthened shell can assure structure to meet the requirement of target reliability.
