Capacity analysis of two-way slab
Capacity analysis of two-way slab
(OP)
I need to check an existing 8" thick two-way concrete slab for an eccentric distributed load of mechenical equipment of 60 PSF. The dead load of the slab is 100 PSF in addition to permanant dead load of 40 PSF. The total load on the panel is 200 Psf. It is a 24'x15' typical interior salb panel. The existing salb was reinforced with #4 @ 12" Each Way.
I have analysed the floor for its capacity using the direct design method of ACI, and found that the existing reinforcement is inadequate.
Is there any other way to check the existing salb for its capacity? whether my calculations are correct, or am I missign something?
Thanks for your time

RE: Capacity analysis of two-way slab
Have a second look at the slab. You might be assuming it to be a simply supported slab which will be a very coservative way of looking at it if the corners of the slab are anchored to the support or are held down by weight above. The corners and edge conditions of a slab are very critical parameters if you want to assess the capacity of it.

If you continue to find the slab is inadequate, perhaps redistribution of moments will help.
