Roof Slab Reinforcement Design

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.

Roof slab reinforcement design.

Identify the type of slab. If reinforced concrete were to be reused strong connections would have to be made between roof and walls. Determine the dead load that is acting on the slab. 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.

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. Design of slab examples and tutorials by sharifah maszura syed mohsin example 1. Find the effective span which is lesser of i distance between centres of bearings and ii clear span and effective depth. Should not be less than 110 mm for rooms should not be less than 75 mm for sunshades.

Slab supported on two sides and bending takes place predominantly in one direction only is called one way slab. Reinforcement detailing of a slab is done based on its support conditions. However the complexity of the generalized approach. Determine h min and round it to higher 10mm multiple.

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. Design procedure of one way slab. Such slabs left unconnected to walls caused many deaths in the 2005 quake from school roof collapses.

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. Slab supported directly by columns are called flat slab. 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.

Slab may be supported on walls or beams or columns. Reinforced concrete slabs are heavier and generate higher seismic forces in an event. Assume the thickness of slab take 4 cm per metre run of the span. 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.
