Rcc roof slab steel design.

Number of required bars formula length of slab spacing 1. B depth of slab. Number of main bars ly spacing 1 4000 150 1 27 nos. 1070 kg steel quantity required for 1000 square feet rcc slab in india and their construction cost is about rs rs 64200 for steel rebar read more if you want to know how much steel required for 1000 sq ft roof slab.

The full form of rcc is reinforced concrete cement. However the complexity of the generalized approach. Construction on site design of rcc structures caption minimum rcc beam size should not be less than 9 x 9 225mm x 225mm with an additional slab thickness of 125 mm i generally use a minimum of 4 bars with 2 bars of 12 mm thickness in the bottom of the beam and 2 bars of 10 mm at the top of the beam. First find number of rods required for main reinforcement and distribution.

Rcc roof slab in the construction industry when they use the word concrete they are talking about reinforced cement concrete also known as rcc. The slab should be provided steel bars to withheld tensile force so this slab is called the rcc slab. Shuttering materials such as wooden ballies planks and iron plates etc. Where reinforcement is called a steel rod.

In m20 ratio of sand cement and aggregate is 1 1 5 3 in this ratio 1 5 part is sand. The reinforced concrete features combined the strength of cement and steel bars which are the basic components of a modern structural design. Following are the rcc slab design and detailing guidelines. Dead load and live load the scope of this subject covers rcc design of all 29 slabs 152 beams 33 columns and 33 footings.

Simply the slab in which steel bars are used is known as rcc slab. Contents reinforced concrete slab design guidelinesa effective span of slab. Raw materials for rcc slab roof. Reinforced concrete slab design and detailing guidelines for depth of slab loads on slab reinforcement guide for one way and two way slabs as per is 456 2000 have been tried to present here.

In steel design subject covers the design of roof truss platform which include the design of floor beams and. According to the 1995 aci code all two way reinforced concrete slab systems including edge supported slabs flat slabs and flat plates are to be analyzed and designed according to one unified method such as direct design method and equivalent frame method. Thickness of slab 150 mm. And design of given project for gravity loads only i e.
