Roof Slab Reinforcement Design

Determine the dead load that is acting on the slab.

Roof slab reinforcement design.

If reinforced concrete were to be reused strong connections would have to be made between roof and walls. Design procedure of one way slab. 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. 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.

Flexural reinforcement must be greater than 0 0018 psi or the shrinkage reinforcement. Find the effective span which is lesser of i distance between centres of bearings and ii clear span and effective depth. The slab has to carry a distributed permanent action of 1 0 kn m2 excluding slab self weight and a variable action of 3. Slabs are constructed to provide flat surfaces usually horizontal in building floors roofs bridges and other types of structures.

Assume the thickness of slab take 4 cm per metre run of the span. Slab supported directly by columns are called flat slab. Slab may be supported on walls or beams or columns. 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.

Slab supported on two sides and bending takes place predominantly in one direction only is called one way slab. However the complexity of the generalized approach. Determine h min and round it to higher 10mm multiple. Should not be less than 110 mm for rooms should not be less than 75 mm for sunshades.

Such slabs left unconnected to walls caused many deaths in the 2005 quake from school roof collapses. Reinforced concrete slabs are heavier and generate higher seismic forces in an event. Identify the type of 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.

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. Simply supported one way slab a rectangular reinforced concrete slab is simply supported on two masonry walls 250 mm thick and 3 75 m apart. However including the beams would effectively transfer a load of slabs to the columns which is good for durability of the structure. Slabs are classified into 16 types.
