Computer simulation of multistory buildings with allowance for wind impact

The article is concerned with the problem of multi-purpose high-rise buildings of 13-23 floors. Six models of the high-rise buildings were studied with the help of the software package “Monomakh”. The models of the multistory buildings have a complex shape, height discontinuity, various structural systems. Vertical temporary loads are of full size and of low value. The influences on the movement of the top of the buildings are studied. They depend upon the strength of the vertical load-bearing structures, material consumption, and the angle of the wind attacks. Displacement of the top of the building depends to a greater degree upon its bearing structures and to a lesser extent upon the temporary load value. The angle of the wind attacks influences displacement of the top of the building. The displacement is maximal when the angle of wind attack equals 135 degrees. For all heights of the building the static constituent is bigger than the pulsating component of the wind load.
