Abstract
This paper presents structural analysis according to Eurocode and SRPS standards. Analysed construction is 40 m high steel chimney, made of 33 m long upper circular cross-section segment of constant diameter D=1834 mm and bottom variable circular cross-section segment of D=2234 mm on the foundation level. Wind loads are dominant loads for this kind of structures. In analyzing workload basic wind speed is thoroughly treated according to SRPS U.C7.110, and respectively wind speed is treated according to Eurocode 1 for the location of Prahovo. Design of model for the effects of its own weight, a constant load and wind load was conducted according to the second order theory for pre-formed load combinations. The load combinations do not contain partial load safety factors. Design of chimney shaft segments are carried out for different ticknes by height of the pillar, for bearing capacity of cross-section, buckling due normal stress, buckling due tangential stress and buckling control is carried out due shear stress.
