One-way slab in Etabs!

One-way slab in Etabs!

One-way slab in Etabs!

(OP)
How can i model a one way slab in Etabs? I read somewhere that i can use membrane element but i am interested in the out-of-plane behavior of the slab. Is it possible to use shell element for a one way slab?

RE: One-way slab in Etabs!

You could always edit the flexural stiffness of the slab, so that it will only span one way. (ie significantly reducing the bending stiffness in one direction).

RE: One-way slab in Etabs!

I have never done it myself but you can assign slab modifiers, I would recommend setting the direction you don't want to consider the slab span to 5 to 10% (0.05 to 0.1). This will be either the M11 or M22 modifier depending on the direction your slab is orientated.
