Design and Application of Lightweight Steel Residential House

This paper presented a design of a steel residential house. H-shaped steel was chosen as the beam and column of the steel frame. End-plate joints and welding node joints were used to connect each other so that the structure could be constructed rapidly and conveniently. PK prestressed concrete composite slab was chosen as the floor and roof slab. PK slab could be produced in factory and dont need formwork assembling and setting and could reduce the amount of work on-site, and could shorten the period of construction effectively. Composite panels with steel truss reinforced concrete and bamboo reinforced ceramic concrete were chosen as exterior walls. Compared with aerated concrete block wall with external insulation, composite panels had the advantages such as lightweight, energy saving, rapid installation, less slit and small thickness of wallboard and better seismic behavior. Application of the technology made the steel residential house a lightweight, energy saving and rapid construction house.
