Description:

Effect of Unanticipated Extreme Loads on the Resilience of Chimneys and Cooling Towers

Abstract
The essential characteristics of extreme loadings such as earthquake, blast and tornado are briefly described. For some of these loading cases, the impact of a significant event on an actual chimney and cooling tower is used to illustrate selected aspects of the structural performance. While chimneys and cooling towers have been successfully constructed worldwide for decades, in the present context of resiliency they both possess an undesirable structural characteristic in that they are globally statically determinate. The response of these structures to extreme events is reviewed with the objective of validating design characteristics that may improve performance under any imaginable loading condition.
The essential characteristics of earthquake, blast and tornado loadings, as they affect the capacity of conventional structures, are briefly described. For some of these loading cases, the impact of a significant event on an actual chimney or cooling tower is used to illustrate selected aspects of the structural performance. The response to these events and their consequences are reviewed, similarities and differences from the code requirements on the lateral load- resisting system are discussed, and multi-hazard commonality characteristics are suggested. In addition, nonlinear analysis techniques that may be applicable to more than one hazard are noted. Lastly, some comments are offered on the concept of resiliency as applied to chimneys and cooling towers.


Bio
Phillip L. Gould joined Washington University in 1966 after completing his B.S. and M.S at the University of Illinois, enjoying a short but rewarding career as a structural engineer, and finishing doctoral studies at Northwestern University. He was the Harold D. Jolley Professor of Civil Engineering from 1981 until 2010, served as department chair for 20 years and is now a Senior Professor.
His research activities have centered on shell analysis with applications to finite element modeling, biomedical engineering, earthquake engineering, and the structural design of thin-shell structures. Dr. Gould is the author of numerous papers and several books, is the founding editor of the prestigious journal, Engineering Structures, and has served as a consultant to industry and to governmental organizations.
