One of seniors told me this. Is this true and can someone provide me with some reference ?

Clarification for Minimum Reinforcement for Raft and Retaining wall
-
The minimum of raft concrete is 0.0018bh. Some engineers argue that the reinforcement taken out from this formula should be distributed between two faces (top and bottom), while others explain this is only for one face (bottom or top only). Also regarding retaining wall, Firstly is the minimum 0.0033bh or 0.0018 ? and is this to be distributed between both faces or single face ? Can the experts please clarify this. Thankyou

Hello experts, Can someone give me any lead on how to calculate shortening of wall in Z direction 1-Due to shrinkage 2-Due to creep wall height is 12ft, thickness 12", and f'c is 6ksi. please help
-
Thankyou for the information. I didn't understood the last part of your answer but got my solution. Very helpful indeed. Keep it up

Hello Experts, I am designing a G+2 denim factory with isolated footing, On the ground floor is a heavy warehouse and lifters will move on it. Do I have to model the plinth level in Etabs model with all the storage loads as defined by codes ? or just simply ignore the plinth level and model the super structure ?

Hello, Can you please tell me why do we place min shrinkage r/f in bottom of continuous footing and not flexural r/f ?

Thankyou soo much,
Can you please also tell me how to transfer loads from slab to beam in a triangular slab manually ? Or is there any way I can calculate steel around beams manually in a triangular slab ? -
The question is not clear...b
!. Do you have a triangular slab sitting on beams on three sides?
!! Do you have a triangular slab sitting on two beams and cantilevering on third side?
!!! Or do you mean a triangular wall sitting on beam?
Assuming (!) above, then:
I have quickly sketched something (sorry its on a tissue) and have attached. It’s simple and logical. You draw the slab yield lines and distribute the load equally to the three beams accordingly, and calculate shear and moment.... or use a computer design programme which will calcualte moment and reinforcement.... always best to do it by hand to at least check the computer output!
One you have have the loading on the beam, you can calculate beam shear and moment and detail steel accordingly and calculate the reinforcement to the code you are working to...
Hope this helps ...?

Also, remember:
Apart from beam reinforcement design, remember you will require top slab reinforcement coming out of your beams into the top of the slab....for the hogging moment at edges & to stop any cracking in top of slab...i.e top reinforcement along all three edges.
In slab bottom reinforcement is needed in middle; Top reinforcement in edges.
