Rcc Roof Slab Thickness

Minimum thickness of concrete slab beam column foundation and other structural members is selected to meet the design requirements as per standard codes.

Rcc roof slab thickness.

Design process includes proper assumption of structural element sizes and then check. Reinforced concrete slabs are heavier and generate higher seismic forces in an event. One way or two way slab. Thickness of the slab is decided based on span to depth ratio specified in is456 2000.

Minimum thickness of concrete structural elements based on aci 318 14 irc 2009 is 456 2000 and ubc 1997 is presented. The maximum diameter of bar used in slab should not exceed 1 8 of the total thickness of slab. Minimum reinforcement is 0 12 for hysd bars and 0 15 for mild steel bars. Ms steel for slab for main bar should be 10mm and for distribution 8mm or 10 mm.

Weight of slab 1 x 1 x slab thickness x rcc density. Rcc slabs the weight of roof slabs is applied as uniform pressure in kn m 2. If reinforced concrete were to be reused strong connections would have to be made between roof and walls. The projecting portion of the slab is cantilever with free support on the masonry wall.

To find out the exact amount it will take to construct an rcc roof slab let. Precautions to be taken during construction of r c c. Thickness of beam and column. The diameter of bar generally used in slabs are.

For analysis purpose it is we consider a 1 m x 1 m square section calculate the volume of the rcc then the same is multiplied with the density for the derivation of pressure in kn m 2. Af math engineering 12 716 views. Such slabs left unconnected to walls caused many deaths in the 2005 quake from school roof collapses. After reading this article you will learn about the r c c.

6 mm 8 mm 10 mm 12mm and 16mm. However you can get a rough estimate with a simple rcc roof slab steel calculation formula. One way concrete slab design part 1 concept explained and minimum slab thickness canadian code duration. The construction cost for rcc roof slab depends on lots of variables like.

For beam it should be 16mm and 12 mm as per span. However in general the thickness of rcc slab should be 4 5 thick.
