Features of the building frame modeling taking into account compliance with the interface nodes wind impacts
The article deals with the question of determining the horizontal deformation of precast concrete skeletons of multi-storey buildings, taking into account the compliance of joints. At the same time, considerable attention is paid to the definition of the load from wind exposure for complex shapes of buildings, with more than two storey floors. Comparison of displacement values obtained as a result of the calculation frame model 30-storey building in a variety of software systems, which showed the need for programs that simulate wind flow around structures. The authors proposed sequence determination movement building frame sequential simulation using software systems with and without taking into account the compliance of joints, the value of which is determined using the stress-strain diagram of concrete in compression of the experimental-theoretical method. The proposed sequence of calculation of precast frame will allow a more accurate assessment of its deformability, to prevent possible accidents during its exploitation.
