Lets understand the ONE WAY slab and TWO WAY slab theory in a practical way.
Let me first take you to the construction site which we visited quite recently .
The slab was almost ready for casting and hence we could see the entire reinforcement in complete details.
NOTE THE BENT UP BARS AT ALL PERIPHERIES.
But before we go further , I think we need to understand what is a BENT UP BAR and why is it provided . Right ?
So , lets first look at the bent bar properly .
A bent up bar is also known as CRANK bar
and is sometimes referred as FLEXURAL STEEL.
Main purpose of a bent up bar is to resist the DIAGONAL SHEAR .
Also note that a bent up bar is ONLY provided in the FLEXURAL MEMBERS like Beams or Slabs.
Now look at the exact shape of the Bent up bar :
This is perhaps the ONLY reinforcement bar which is BENT at 45 degrees with the horizontal.
Now , let us also look at the Bent up bar provided in a BEAM.
Now , with this background about the bent up bars , let us see the ground rules of the ONE way and TWO way slabs.
THANK YOU SOOOOO MUCH EVERY ONE INVOLVED.
