Abstract:The project of steel indirect air cooling tower for Huadian Tuyou power plant was studied in perspectives of model selection of structural system, load analysis, seismic design and design method of prefabricated joint. In addition, the overall performance of the structure was optimized by wind tunnel test and wind-induced response analysis. The durability of the aluminum alloy panel and its connections were solved by reliability test of the substructure of the enclosure system. A reasonable structure system for indirect air cooling tower of steel structure in power plant was put forward to solve the related connection structure problems and better reflect the characteristics of light weight, good seismic performance, fast assembly speed, environmental protection and energy saving of steel structure air cooling tower. The structural system, design method and joint connection structure adopted in the project can be used for reference for similar projects.
Keywords:structural system; load; prefabricated joint; panel substructure
