Roof Slab Reinforcement Details

Reinforcement details of one way slab.

Roof slab reinforcement details.

Slab containing supports on less than 4 sides can be designed as the one way slab. Detailing of slab openings of 450mm to 900mm. Slab supported directly by columns are called flat slab. Reinforcement details of concrete beams and slabs should specify clearly about cover to reinforcement length of reinforcement curtailment of reinforcement number and diameter of reinforcement to be provided.

Slab supported on two sides and bending takes place predominantly in one direction only is called one way slab. Reinforcement details of one way slab. Detailing of medium slab openings. Figure 1 depicts the reinforcement details of a one way slab.

Reinforcement detailing of a slab is done based on its support conditions. For slabs with openings more than 450mm and less 900mm at least one half the quantity of main steel reinforcement intersected by the opening is provided parallel to the main reinforcement bars on each side of the opening extending a length of development length l d beyond edges of the opening on both top. Rcc roof slab reinforcement details if you follow the minimum standards for structural design for modern day buildings you can opt for creating the rcc without a beam it is called a flat slab. As shown in the figure above in the one way slab the main bars cranked bars are provided on the shorter side.

However including the beams would effectively transfer a load of slabs to the columns which is good for durability of the structure.
