Roof slab steel details.

Bending and bowing aluminum and steel roofing and siding sheets are rollformed from hardened tempered metal for maximum strength. Minimum reinforcement is 0 12 for hysd bars and 0 15 for mild steel bars. Best materials ph. Steel roof section design dwg file.

The maximum diameter of bar used in slab should not exceed 1 8 of the total thickness of slab. 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. 6 mm 8 mm 10 mm 12mm and 16mm. Design draw in autocad format.

Steel roof section details steel roof section design detail steel bar use make a slab amp. The dwg files are compatible back to autocad 2000. Metal should not be re bent once it has been formed nor should it be folded back on itself. 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.

Main bar distribution bar difference top and bottom clear cover is 25 mm consider development length as 40 d thickness of slab 150 mm. Thickness of the slab is decided based on span to depth ratio specified in is456 2000.
