Thank you both, @Celt83 I'm trying to understand your formula from the link, thank you. If I am not mistaken, the centroid of a triangular shape is: This is why I don't understand that Fc is located at x1/2 from NA..I'm a little bit confused [3eyes]

Hello Im trying to calculate stresses in SLS for a bending square section in reinforced concrete. It involves to find the neutral axis which is possible with static moment equation. Here is the distribution of stresses for a square section in diagonal plan from a book: First, I don't...

Thank you for your help. @retired13 I agree, thank you for your explications. (I made a mistake when I create my account, I'm structural engineer; I will correct it right away ;-)).

Thank you for your answer. This is why I’m asking I’m not sure to understand. My question is, if reinforcement methods are not describ for a linear diagram( trapezoidal or triangular) and only uniform, is there any sens to optimize the cross section of shallow foundations with trapezoidal and...

Thank you for the answer. For a shallow foundation with bending moment in one direction we can have a trapezoidal or triangular soil pressure depending on eccentricity value : The NF94-261 is an annex of Eurocode 7. We find that Meyerhof’s method can be used to simplify the distribution soil...

Hi, I work in a French office and I have questions about foundation design with EC7 and EC2. I'm studying column foundations with eccentricity to program an Excel sheet. I configured Meyerhoff, trapezoidal and triangular pressure distribution for combined bending to verify the soil pressure...

please , do you have any idea?
