Buildings with Open Plan Floors and Integrated Load-Bearing Structures

摘要

The paper considers a structural concept for multistorey buildings with free floor plan and the new type of large-size load-bearing structures.The characteristic of the structural concept is that the main spatial reinforcing member for adjacent storeys in building is a steel truss.Such approach makes it possible to organize large-span space through the floor and it can be used for different purposes,for example,for shopping area,ice or roller-skating rinks,open space offices.The authors designed structural node connections including resting of floor slab on truss chords,as well as joining of steel truss to shotcrete filled rectangular tubes.Parameters of the most cost-efficient cast-in-place floor slab by corrugated deck have been determined.
