Roof Slab Reinforcement Design

Slabs are classified into 16 types.

Roof slab reinforcement design.

Slab supported directly by columns are called 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. Slab may be supported on walls or beams or columns. Slab supported on two sides and bending takes place predominantly in one direction only is called one way 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. However the complexity of the generalized approach. Design procedure of one way slab.

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. If reinforced concrete were to be reused strong connections would have to be made between roof and walls.

Slabs are constructed to provide flat surfaces usually horizontal in building floors roofs bridges and other types of structures. 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. 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. Design of slab examples and tutorials by sharifah maszura syed mohsin example 1.

Assume the thickness of slab take 4 cm per metre run of the span. Identify the type of 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. Find the effective span which is lesser of i distance between centres of bearings and ii clear span and effective depth.

Reinforcement detailing of a slab is done based on its support conditions. 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. 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.
