When i model two way solid slab .. to compare robot results with manual calcuations , there's some strange results ?!
1- why is robot locked the concrete options by default and can't determine the concrete strength as i want ?
2-the results of punching shear it's not matched with manual calculation and SAFE results .. but the results it's not too large as robot !
3- if the value of punching about 1.1 or 1.2 .. can i ignore it or i can't ?
4- what about panel cuts to match it with column strip and middle strip
thanks in advance
