NON-LINEAR ANALYSIS OF REINFORCED CONCRETE CHIMNEY

A chimney is a structure which provides ventilation for hot gases from industries to the outside atmosphere which are typically vertical, or as near as possible to vertical, to ensure that the gases flow smoothly. Tall reinforced concrete chimney are used in thermal power plant as well as in some important industries as to dispose the pollutant smoke to the higher elevation without contaminate to atmospheric air. To maintain this, chimneys are constructed as much as tall. As a result, chimneys are tall slender structures. They have different associated structural problems and must be treated separately from other form of tower structures. Collapse of this chimney structures wo uld lead to shut down of whole thermal power plant and important industries.
