How many floors can light steel villas be built
Residential buildings with a structural system completely using light steel rib generally can reach 6 storeys. North America has successfully applied this system to build 8-story hotels. The light steel structure can be combined with other structural systems, such as hot-rolled H-beam or reinforced concrete frame-shear system, to form a composite structural system suitable for high-rise residential buildings.

house load calculation
general calculation principles
The load mainly includes: vertical permanent load, including self-weight and service load; horizontal load, wind load; earthquake horizontal and vertical action. The internal force and displacement of the steel structure are generally calculated by the elastic method.
Multi-rise steel structure system
Flexibility as needed
For buildings with few floors and low seismic fortification requirements, priority should be given to adopting a frame structure system, and buildings with high seismic fortification requirements should be given priority to adopt a frame-support structure system.
Design method of steel frame column
Section form selection
There are H-beam section, cross-section steel section, square tube section, round tube section, etc. The section can be changed roughly every 3-4 layers. The seismic structure system is mainly based on central support + diagonal support.
Composite floors and composite beams
Consider the stress stage
The stress model analysis of the profiled steel plate only considers the transfer of the load along the direction of the strong side (one-way plate), because the section stiffness in the direction of the strong side is much greater than that of the direction of the weak side.
beam to column connection
flexible / rigid
Fog usually adopts the connection method of column through, and can be divided into flexible connection, semi-rigid connection, rigid connection, etc. according to the rotational stiffness of the connection.
Node construction improvements
Science and Safety
The beam flange is partially weakened, forming a bone-shaped connection, and the plastic hinge moves outward from the beam end. The haunches are added at the ends of the beams, and the plastic hinges are moved outward for structural reinforcement.
