A chimney is a means by which waste gases produced due to industrial processes are discharged to the
atmosphere. Height of the chimney is kept such that the gases get diluted due to atmospheric turbulence. Chimney is
particularly susceptible to the wind pressures so it is important to correctly estimate the design wind loads. Chimney is a
vertical cantilevered shell pierced by openings where necessary and subjected to large temperature gradients. The prime
focus of the present major project work is to study the behaviour of chimney structure under the effect of wind loads,
earthquake loads and temperature gradients. Chimney has been modeled in STAAD.Pro V8i using the lumped mass
modeling approach, to calculate dynamic properties useful for seismic and wind analysis. Parametric study has also
been carried out for an RCC chimney for different geometric variation and effect of opening in chimney
