Helicopter hangar in Kiev region
Object's characteristics: Building with a span of 48 meters, length of 30 meters and height to bottom part of truss of 7.2 meters. Frame is steely. Heavy truss with a span of 48 meters with chords and web of H-shaped profile (welded H-beam), that carries a load from half a building, is provided from gates side. The remaining part of a building is post-and-beam system made of rafter supports and rafters, which bear on truss and on columns.
Analysis has been performed for spatial model for concurrent action of the following loads: - Dead loads (weight of steel frame and roof enclosure structures, walls and gates); - Snow loads by sections (8 mutually complementary loads); - Wind loads in different directions. In the process, there was considered a variant with opened and closed gates (6 mutually exclusive loading states); - Hangers of equipment and supplies by sections; - Permissible difference of settlements.
