RE: Critical section in Footings

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Ashraf,

I would be interested in seeing that FEM solution because I do not think the peak moment will actually be at the face of the column for a two way slab in such an analysis, even with the stiff supports modelled (something most FEM designers ignore).

Refer to any good book on concrete design. (If you are in India, you can refer to Reinforced Concrete design by S.U.Pillai and D.Menon ,By Tata McGraw- Hill.)
 
The reason for taking moment at the face of column is the footing slab bends upward into a saucer-like shape on account of net soil pressure from below. Based on extensive tests it has been determined that on footing supporting  column the critical section for BM  will be at the face of column.
 
If you make a 3 D analysis  you can verify that maximum moment will be at the face of the column.

Can anybody give me an idea or refer to some literature on:

Why  the critical section for moment in footing(or a flat slab) taken at the face of the column?

Thanks
