Roof Slab Steel Details

Thickness of the slab is decided based on span to depth ratio specified in is456 2000.

Roof slab steel details.

Minimum reinforcement is 0 12 for hysd bars and 0 15 for mild steel bars. 6 mm 8 mm 10 mm 12mm and 16mm. The diameter of bar generally used in slabs are. Best materials ph.

Bending and bowing aluminum and steel roofing and siding sheets are rollformed from hardened tempered metal for maximum strength. Maximum spacing of main bar is restricted to 3 times effective depth or 300 mm whichever is less. Main bars are 12 mm in diameter 150 mm centre to centre spacing distribution bars are 8 mm in diameter 150 mm centre to centre spacing. This method has been used extensively since 1963 for slabs supported at the edges by walls steel beams or monolithic concrete beams having a total depth not less than about 3 times the slab thickness.

Steel roof section design dwg file. Design draw in autocad format. Main bar distribution bar difference top and bottom clear cover is 25 mm consider development length as 40 d thickness of slab 150 mm. Metal should not be re bent once it has been formed nor should it be folded back on itself.

The maximum diameter of bar used in slab should not exceed 1 8 of the total thickness of slab. These cad drawings are available to purchase and download immediately spend more time designing and less time drawing we are dedicated to be.
