two way rib system question
two way rib system question
(OP)
Hello all
Here is the deal. I have a chem. Lab roof that is 15mx13.2m. the lab is column free and the roof carries the offices in the above floor. Go to the URL below to view a plan of the Chem lab.

My questions are:
How can you establish the depth of the ribs according to deflection requirements and is there any ACI refrence?
How would you calculate the self weight of such system after you establish all dimensions needed (depth, spacing, and beam thicknesses)?
I hope my case is clear to you all

First , I want to thank you for your reply. I have contacted some of the manufacurers here in Kuwait City and none of them have provided me with such info. all they say is "you specify the size and we will make it for you".
let me address the question to you and all the readers in anotherway.
how can you calculate the deflection in a waffle slab or the two way system i have provided the link for?
Thank you all
