Steel bar for floor slab diagram. Concrete surfaces expected to carry heavy trucks or machinery do need concrete rebar reinforcement. Not all surfaces need concrete rebar reinforcement but adding it makes concrete stronger and more resistant to large cracks. For your better understanding let s take this example. The main function of an owsj is to provide direct support for roof or floor deck and to transfer the load imposed on the deck to the structural frame i e.
In structural engineering the open web steel joist owsj is a lightweight steel truss consisting in the standard form of parallel chords and a triangulated web system proportioned to span between bearing points. This tool can design a typical interior bay and optimize the results for either the overall weight or the relative cost of the framing system. The maximum diameter of bar used in slab should not exceed 1 8 of the total thickness of slab. Main reinforcements bars we provide in the shorter span of the slabs and the bars will along the longer span of the slab in the long span of the slab the steel we provide known as distribution steel which doesn t help to carry any types of load and the only function to distribute the load or counter the shrinkage stresses.
Thickness of the slab is decided based on span to depth ratio specified in is456 2000. The percentage of reinforcing refers to the cross sectional area of the steel for a given width of slab divided by the cross sectional area of the slab area considered. Floor framing formerly known as parametric bay studies can help engineers determine optimal composite steel and concrete slab on metal deck floor framing. 6 mm 8 mm 10 mm 12mm and 16mm.
Now calculate bar bending schedule for two way slab. Two way slab reinforcement detailing. Floor slab 1 two way slab bars along x axis bars along y axis total wt of bars 150 285 150 091 300 376kgs for floor slab 2 one way slab as per the above. Let s take an example the below two way slab diagram.
Compute the total wt of steel required for slab reinforcement. Please refer the bar bending shape code steel weight calculation post. 405 2z bars in section 405 2aa bending diagram examples 405 2bb cutting diagram transverse steel in bridge deck 405 2cc cutting diagram hammerhead stem pier 405 2dd reinforced concrete bridge approach bill of materials 405 3a haunch configurations for reinforced concrete slab superstructures 405 3b typical reinforced concrete slab. The diameter of bar generally used in slabs are.
Rebar reinforcement has been used to provide concrete with the support necessary to withstand tension forces for over 150 years. For example if a 6 inch thick slab is used with 3 rebar at 18 inches on center the percentage of steel for a 12 inch width would be. Find out the no.
