One Way Slab And Two Way Slab Formula

Chajjas and verandahs are a practical example of one way slab.

One way slab and two way slab formula. I e w a and w b. What is the formula for taking load from two way slab beam. 0 1 x 25 2 5 kn m 2 100 mm thick slab live load on slab. In this civil engineering article you will gather knowledge on how to work out the quantity of steel inside a flat one way or two way slab.

Load transfer in a one way slab b two way slab nilson fig. Determine the minimum thickness of slab from serviceability criteria of deflection control. One way slab design steps. Example of two way slabs is slabs used in the floor construction of multi storey buildings.

Two way slab is economical for the panel sizes up to 6m x 6m. This video explains the load distribution on two way slab load derivations. Calculate aspect ratio and determine either it is one way or two way slab. Abcd is a two way slab l b 2 assume.

Two way slab is a slab supported by beams on all the four sides and the loads are carried by the supports along with both directions it is known as two way slab. Suppose there are two slabs one is big for room and other is small for bathroom. The dimension of the big slab is 5m x 3m and the dimension of small slab is 2 5m x 1 5m. If l b the ratio is greater than or equal 2 or then it is considered a one way slab.

Dead load of slab. In two way slab the ratio of longer span l to shorter span b is less than 2. What is the formula for taking load from two way slab beam. One way slab and two way slab.

If l b the ratio is less than 2 then it is considered a two way slab. In one way slab the main reinforcement is provided in a short span and distribution reinforcement is provided in a long span. While designing two way slabs more steel is used hence the depth of the slab decreases. Basically the depth of a slab is very small compared to its depth.

For uniformly distributed loads of w per square foot of the slab each strip acts approximately like a simple beam uniformly loaded by its share of w. 1 a one way slab having total depth one way slabs two design methods to rc slabs on secondary ppt slender columns and two way slabs rc rectangular slabs subjected to patch. Slabs may be supported by rcc beams columns steel beams etc. Slab is an important structural element generally constructed horizontally to provide flat surfaces such as roof ceiling floor etc.

Aspect ratio longer span shorter span if greater than equal to 2 it is one way slab and if less it is two way slab. 3 kn m 2 total load. There are mainly two types of slabs 1.
