Roof Slab Reinforcement Design

Determine the dead load that is acting on the slab.

Roof slab reinforcement design.

However including the beams would effectively transfer a load of slabs to the columns which is good for durability of the structure. 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. Such slabs left unconnected to walls caused many deaths in the 2005 quake from school roof collapses. Reinforcement detailing of a slab is done based on its support conditions.

The slab has to carry a distributed permanent action of 1 0 kn m2 excluding slab self weight and a variable action of 3. This is the design of roof how the reinforcement has been lated over here and how to be the covering lated over is 6 x6 inch and used 10 and 12 mm diameter bars. Reinforced concrete slabs are heavier and generate higher seismic forces in an event. The slab may be supported by walls or by reinforced concrete beams usually cast monolithically with the slab or by structural steel beams or by columns or by the ground.

Slab may be supported on walls or beams or columns. Steps to be followed in the design of slab assuming suitable bearings not less than 10cm find the span of the slab between the centers of bearings. Should not be less than 110 mm for rooms should not be less than 75 mm for sunshades. However the complexity of the generalized approach.

Design procedure of one way slab. Slab supported on two sides and bending takes place predominantly in one direction only is called one way slab. Identify the type of slab. Flexural reinforcement must be greater than 0 0018 psi or the shrinkage reinforcement.

Assume the thickness of slab take 4 cm per metre run of the span. Design of slab examples and tutorials by sharifah maszura syed mohsin example 1. Determine h min and round it to higher 10mm multiple. Slabs are constructed to provide flat surfaces usually horizontal in building floors roofs bridges and other types of structures.

Find the effective span which is lesser of i distance between centres of bearings and ii clear span and effective depth. Slab supported directly by columns are called flat slab. In this video we learn how to reinforcement design in slab in autocad in hindi dear all slab two type ke hote hain one way slab two way slab slab me reinforc. If reinforced concrete were to be reused strong connections would have to be made between roof and walls.
