Abstract

Chimneys are very tall and slender structures. As per ISIS 4998 (Part 1): 1992, major loads considered for analysis of chimneys are wind loads and earthquake load. Each of them is combined with dead load to get the most critical load for designing a chimney. This paper presents the analysis of a slender RCC chimney with a combination of dead load and wind load. Firstly beam column theory is applied on a tall slender chimney and general equations are developed for bending moment with and without the consideration of second order analysis. Validation of same is done by a typical problem of a tall chimney. Dead load of the structure is calculated by using frustum of a cone method. Wind load is calculated as per IS 875 (part3)-1987. Analysis is carried out by the combination of dead load and wind load. The dynamic effect is ignored. Bending moments are calculated manually by using beam column theory for first and second order analysis of chimney. These results are later compared with STAAD PRO results.
