two way slab design calculations

[archdevil]

Two way slab is a slab supported by beams on all the four sides and the loads are carried by the supports along both directions, it is known as two way slab. In two way slab, the ratio of longer span (to shorter span is less than 2. In two way slabs, load will be carried in both the directions

kindly refer the attached file for two way lb deign

i have also make a design sheet check out this one

Design Two Way Slab​

The most difficult and tedious design of building construction is Design Two way slab because of the various condition of the design step and also repeated and long step

But But But
This problem is no more because you come to my blog so that you will find an Excel Design Sheet

No one gives a personal design sheet because of

1) Monopoly
2) Hesitated to share the personal skill
3) they try to filter their position

But my goal is very different which shown top of my site CIVIL EXPERIENCE

Only one Step for Design Two Way Slab​

just add a few information Which shown in Image like
Grade of concrete ƒck,
Grade of Steel ƒy,
Concrete cover,
Clear long spam,
Clear short spam,
With of supporting beam,
live load,
Floor finish load,
Diameter of main and distribution bar, and
assume thickness of the slab

and what YOU WILL SHOWN RESULT OF DESIGN TWO WAY SLAB IN JUST a FEW SECOND



The calculation step which I cover in excel sheet is listed below

1. • Effective Depth
   • Load calculation
   • Support condition
   • B.M. Consideration
   • Check for deflection
   • Check for Shear

So you can easily design the best structural and economical design of Two Way Slab Reinforcement Details Design

How to use sheet for design​

You only field the nominal data which in yellow and blue colors

also i write list which you enter data

Grade of concrete ƒck =
Grade of Steel ƒy =
Concrete cover =
Clear Short Span Lx=
Clear Long Span Ly =
Width of Supporting Beam =
Assume Thickness of Slab =
Dia. of Reinforcement Bar=
Super Imposed Load =
Floor Finish Load =

then carefully

Area of Steel along Short Span = ( which you want to provide )
Minimum Area of Steel = ( which you want to provide )
Provide Area of Steel = ( after see the result Area of Steel along Short Span & Minimum Area of Steel carefully select the Provide area of steel which we follow for design )
Width of Middle Strip =
