One-way & Two-way Slabs Directions

[Anonymous]

in the name of  GOD  .

hello ta all.

in attached picture I draw a one-way slab in left and draw a two-way slab in right. (see attached picture.)

questions :

1 ) how can I understand which slab is one-way & which slab is two-way from appearence of those and without properties windows of those ??

2 ) how can I understand the direction of load transfer of one-way slab from appearence of that and without properties window of that ?? (for example in attached picture, what's the direction of load transfer of one-way slab (on x or on y direction ) ?

3 ) how can I rotate the direction of load transfer of one-way slab ??

thanks beforehand for your appropriate answers... 

best regards.

Re 2

• One-way X - anisotropic: parallel to the local x axis of a panel
• One-way Y - anisotropic: parallel to the local y axis of a panel and perpendicular to the local x axis of a panel. http://docs.autodesk.com/RSAPRO/2014/ENU/filesROBOT/GUID-2F6BADFE-F90B-46AA-97F8-227926DB9A7C.htm

First and foremost i would like to say very detailed explanation you have got there, thanks. However, I think applying "Re 2" i.e the One way X/One way Y to a floor panel would convert it to a cladding, which would defeat the purpose since cladding do not participate in the load capacity of a structure therefore one would be unable to for example get floor analysis results in the form of maps. Is there any other way to go around this for floor panels?

If I understood you correctly,
