5.2.2 MATERIALS
The Hambro top chord acts as a continuous shear connector.
Bottom chord angles and web members are hot or cold
rolled sections, minimum yield Fy = 380 MPa (55 ksi) and
350 MPa (50 ksi) for rods.
5.2.3 WEB GEOMETRY
The web geometry is exactly the same of D500TM presented in page 33.
5.2.4 JOIST SPACING
Between 300 mm (1’-0”) and 1 450 mm (4’-9”) according
to the steel deck capacity in single span. The standard
spacing is 1 220 mm (4’-0”).
5.2.5 SPAN AND DEPTH
Span: Up to 13 100 mm (43’-0”)
