Dynamic Analysis of RCC Chimney- a review

Chimneys or stacks are very essential industrial structures used for the emission of toxic gases or smoke from a boiler, stove, furnace or fireplace to a larger elevation such that the gases should not contaminate the surrounding environment. These structures are generally tall, slender in nature and consist of circular or cylindrical cross-sections. Different types of construction materials, such as concrete, steel, brick masonry, are used to construct chimneys. Steel chimneys are preferably suited for process works where a short term heat-up period and inadequate thermal capacity are required. Also steel chimneys are more economical up to a height of 40m-45m. Usually chimneys are almost vertical in order to ensure that the hot gases should flow smoothly. The present paper comprises of literature review of latest papers published in the field of industrial chimneys. This study offers a comprehensive review of the research papers published in the field of dynamic analysis carried out on the chimneys. The current review article gives the latest information and developments taken place in chimney analysis and design. The paper mainly focuses on dynamic analysis, linear and non-linear analysis, soil structure interaction studies, Seismic and wind analysis etc. The paper gives a complete collection of the studies carried out on dynamic analysis and would give an updated material for researchers.
