when you model as a membrane element, you do not capture the true displacements and moments acting on the slab. So how do one go about analyzing and designing the slab?
Hi all,
When is it most appropriate to model a concrete slab with a membrane or a shell(thin) element. For example, do you model a 150mm thick concrete slab with a membrane or shell element.
desertfox, the analysis was done at the ultimate limit state (ULS) which is 1.4*Deal load (BS8110). the shear force value is not the problem just the mirrored diagram.
desertfox,
just uploaded the reactions.
The absolute values are correct, the problem is just the sign convention. http://files.engineering.com/getfile.aspx?folder=15b60fa0-d8c3-4bc2-bff2-94386d57f3f9&file=REACTIONS.bmp
hi guys, thanks for your contributions
just came back from work so couldn't reply earlier.
The origin of the beam is on the left hand side, with the y-axis pointing inwards into the screen (front face).
hi guys
I'm a new user of the site and I need a little help.
I did a quick analysis of a simply supported beam but the shear force diagram is mirrored i.e. negative shear force on the left support is supposed to be positive and the positive on the right support negative.
Is there any way of...
