ANALYSIS OF SELF SUPPORTING STEEL CHIMNEY

Each structure is to be designed for strength, limiting deflection, and durability. The function and aesthetics of structures should keep in consideration during achieving this strength, deformation and durability. It may possible when the structural engineer had quite knowledge about architectural requirements. In case of high-rise structure, certain failures may occur due to lateral loads. The lateral loads are almost wind and earthquake, whose main horizontal force component acting on the different members of structure. The lateral force effects due to wind and earthquake loads are usually analyzed as an equivalent static load in most type of high-rise structure. These structures are designed in such a way that its every component must resist two types of loads like vertical Load due to gravity and lateral load due to earthquake and wind. The reinforced concrete chimney shell, which transfer vertical load and lateral load to the foundation. The present study is on the analysis of cantilever reinforced concrete chimney with variation in geometry and different orientation, when they are subjected to the lateral loads. This report shows the certain design values for different configurations of chimney structures which may take consideration for foundation designing work. The effects of lateral force due to wind and earthquake loads are analyzed by an equivalent static load method and dynamic analysis by response spectrum method. The present study is carried for the region Nashik, district of Maharashtra state in India. According to which wind load and earthquake load parameters were considered as per IS code such as IS 4998(part-1):1992, IS 1893 (part-4):2005 and IS 875(part-3). The present study is carried only to study the merits and demerits of these types of chimney configuration based on the analysis, for such terrain conditions.
