Abstract
The feeling of the need to build longer cooling towers increases with the development of the capacity of hydropower plants. So the engineers are trying to design leaner towers, with more buckling resistance using environmental hardening rings. Several studies have investigated the effect of wind strength on these structures, but the effect of seismic acceleration on these structures has been less studied. In this study, by investigating the results of linear spectral dynamic analysis, the optimum location of environmental hardening rings is determined under the influence of earthquake acceleration. The effect of thickness and number of hardening rings on the performance of the tower is also investigated, and the optimum relationship between these two parameters is extracted technically and economically. Different analytical methods can be used to investigate this issue, but using the spectral analysis method besides considering the buckling effects of the tower crust is the most appropriate analytical method for these types of structures.
Highlights
The hardening ring is an environmental hardening incorporated into the inner part of the concrete cooling tower shell
SHELL BUCKLING ANALYSIS In order to determine the best location of hardening rings, the shell buckling analysis was initially performed without any hardening rings under unit load caused by seismic acceleration in the X direction
The following results were obtained from the conducted studies: - The best location for the environmental hardening rings will vary depending on the number of hardening rings
Summary
The hardening ring is an environmental hardening incorporated into the inner part of the concrete cooling tower shell. The increase in the capacity of the power plants and the need to increase the height of these towers led to maintaining the stability of the shell as it is one of the most important issues in the design of the structure and the designers used environmental Hardening rings to solve this problem [1, 2]. There are various methods for analyzing this structure, such as spectral analysis and time history methods. The design spectral method is the most logical and economical method for analyzing seismic cooling towers [3]
