Dear Hiren
If it is raft footing, yes we need not have the movement joint thru it. But where rafts are not provided, and where foundation-soil is susceptible to significant settlements, it is better to have independent footings to avoid undesirable forces due to differential movements in superstructure.

J.Y.Desai

Dear friends,

Can we have common footing for columns of buildings, which are seperated by movemement joints of about 3;quot;(75mm)?

Dear Hiren,
Design a single foundation with TWIN column - Design it like a combimed
footing - cg needs to be maintained of footing with center of load -

Dear Kamal,

You have not interpreted my question correctly, still let me know how you will calculate C.G. for two columns having diffren axial loads, Mx and My and these values are diffren for 21 loadcases.

One footing may accommodate 2 columns separated by a joint for movement. The footing has to be designed for the loads and moments from the two columns.

Well the footing has to carry the loads of both the footings , this is
acceptable, but the original question was whether it is practical or is
it necessary to insist that moments from all the load cases be also
checked for and that is where the engineer's decision and judjement
lies.Many people have always checked only for DL+ll whereas many clients
insist that all the load combos for all the columns be checked and many
a times, the client wins and u hav to do it that way. It is only here
that Vipuls reasoning makes lot of sense to me.

Dear Mr. Hiren Desai

Yes, you can and actually must provide a common footing for columns
seperated by an expansion joint of 75mm. In fact, below the ground level you
can have a common pedestal which will act as a single column pedestal. If
you have different axial loads on each column above the ground level, their
footing has to be designed for one worst load case and checked for other
combinations.

regards
Bimal Shah
