Multi story steel structure building can be used as parking lot, office building, steel warehouse etc,.

For super high-rise steel structures, wind loads often play a controlling role, and it is of great significance to choose a shape with a small wind pressure; under certain conditions, the cross-wind vibration effect of the structure caused by eddy current shedding is very significant. The structure is flat, the selection of the facade and the angle The partial treatment will have a significant impact on the cross-wind vibration, and the cross-wind vibration effect of wind-sensitive structures should be studied through aeroelastic model wind tunnel test or numerical simulation.

When multi-story steel structures are set up with basements, the houses are generally tall, and the steel frame columns should extend to the basement level. In the frame-support structure, the supports arranged continuously in the vertical direction, in order to avoid the formation of sudden changes in stiffness at the bottom layer with the greatest seismic response, which is disadvantageous to earthquake resistance, the supports need to be extended to the basement.
