I have designed a trapezoidal footing and it is showing Shear Failure (under show table option) I have increased the thickness of footing but it is still showing, now what should I do to redesign the footing?
Very helpful tutorial, I was working on safe footings basically isolated, after running i am getting unusual sbc values. Could you please help in that.. what might be the reason?
Very good Video tutorial for Combined footing I would like to know detailing procedure as it is showing only bottom reinforcement and no details about shear reinforcement. How to calculate shear reinforcement manually ? I will be waiting for your reply Sir.
In real structures, there is an extremely stiff region within the connections which join columns to slabs. The "Col_Stiff" elements are stiff area elements in which the software amplifies moment of inertia by 100 times to capture the increased stiffness of these connections. The effects associated with modeling these increased stiffness properties within connections include the following: 1. Deflections are more realistic and less conservative in magnitude. 2. Rebar design is also less conservative since reinforcement is designed according to response at the face of the column, and not at the center line of the support. 3. Punching-shear results will change since the stiffness of the areas around the punching-shear perimeter change.
Sir excellent tutorial. When we design from etabs or STAAD, we consider max vertical reaction of worst case. So where should be that entered? In dead load value or live load value or We should define load combination separately
FINALLY WE HEAR YOUR VOICE MAN
Does this model considered the column stump? if not, how do you do it
How do you make number of reinforcement equal on both sides espacially on square footings?

Which one is safe/good for design combined footing strip based or Finite element method ?

If load size is not square then how then how can I enter that load size like if column size is in 300x500mm please reply.

the dead and live load you took form etabs design, was those load factored of unfactored ?
it is unfactored
Thanks to you for sharing
How to check one way shear. Punching shows two way shear .
would you please be more specific even in your future videos in the final stage while showing the reinforcement !! thank you
Thanks very useful. Why oneway shear check didn't considered? Waiting for your kind reply
Why have you defined column as slab stiff? This is the only part I did not get in this brilliant tutorial. Thanks. Waiting for your kind reply.

When load import from etabs,
At that time also do we need to assign stiff?
You can assign stiff to get proper interpretation of moment diagram around the stiff portion.
safe software please?
Dear Sir good morning sound is very low
Can u upload the csi safe foundation design as per is code
Noted.
use service load in P
