Hi there, it cannot fail over the column unless there's also a yield line at this point from the right angled corner to the column. This would be a dotted line like that which would occur at the fixed support (hogging)

Hi there, I raised the model higher and it seems that a line forms at the 90 degree corner and then branches out into the two lines I have drawn. Is this correct? Sorry I mean that it forms at a 45 degree angle out of the right angle and makes a "Y" shape.

Hi there, thanks again, yes our tutor has told us that it can be used but you must be careful in identifying all possible failures and not just designing for one as it may not be the worst case. I have made a quick model triangle and put blutack under for the column and wedged the other...

Hi there, thanks for the help, no dimensions have been shown for any so it is pretty much trial and error for this part at the moment, I think its more to show that you can show why a certain failure can occur. Using the information you have provided I assume that the yield lines span from...

Homework Statement We were given many different slab sizes, shapes etc and asked to analyse them using Work = Energy equilibrium checks to find q, the maximum load per m^2 the slab can take. The first part was to show the fracture lines to use for analysis but I am stuck on one of them. I have...

For anyone else needing to know this its 3ei(delta)/L squared :) and 0 for the pin.

Homework Statement I have a sway case beam as in the image below, but do not know the equation for the pinned joints. We were told Moment (AB) = 6EI(delta)/Lsquared for fixed ends such as AB and BA but not told the moment equation for CF for example. I am assuming FC = 0 due to no moment at...
