Composite structures - Composite steel-concrete construction in buildings
Sets out minimum requirements for the design, detailing and construction of composite steel-concrete members (beams, columns, slabs, joints) in buildings. The Standard is to be used by structural engineers when designing steel framed building structures. It does not cover the design of composite beams and columns where the elements of the steel section are less than 3 mm thick or the value of the yield stress (fy) assumed in design exceeds 690 MPa. It also does not cover composite beams and columns where the concrete characteristic compressive strength at 28 days is outside the range of 20 MPa to 100 MPa.
