Two way concrete floor slab with beams design and detailing csa a23 3 14 design the slab system shown in figure 1 for an intermediate floor where the story height 3 7 m column cross sectional dimensions 450 mm 450 mm edge beam dimensions 350 mm 700 mm interior beam dimensions 350 mm x 500 mm and unfactored live load 4 8 kn m2.
Two way roof slab design.
Two way slabs are supported on unyielding supports on all four sides and the ratio of longer span to shorter span is less than 2.
In this video we will discuss on design of two way rcc slab.
This method was provided in the american concrete institute aci in 1963 to design two way slabs carried by steel beams deep beam or walls.
For this slab panel a has two discontinuous exterior edges and two continuous interior edges panel b has one discontinuous and three continuous edges while the interior panel c has all edges continuous.
The slab is known as two way slab when the ratio of the long span is less than 2 and in floor of multi story buildings this type of slabs are mostly used.
More realistic scenario where a system of beams supports a two way slab.

Nonetheless the coefficient method is not included in the current edition of the aci code.
Here we discuss about the example of two way slab design.
This method has been used extensively since 1963 for slabs supported at the.
Direct design method of the present code has led many engineers to continue to use the design method of the 1963 aci code for the special case of two way slabs supported on four sides of each slab panel by relatively deep stiff edge beams.
The coefficient method may be the simplest easiest and the quickest approach for the design of two way slab supported by edge beam on all slab sides.
Detailing drawing of slab is also explained.
