This paper describes the model tests conducted in the Wind Engineering Laboratory of the Cracow University of Technology aimed at determining the shape coefficients of snow load on high-rise buildings of The Warsaw Hub. The shape coefficient was measured at two different situations: snow precipitation and its subsequent redistribution. The model tests were conducted independently for rooftops and terraces in the scale of 1:120 and for the neighbouring area of the buildings in the scale of 1:300. The results allowed for creation of snow shape coefficient maps on the investigated areas both for snow precipitation and redistribution for the use of designers, constructors and architects.
