You can use spring supports.

SAP2000

The open-source FEA software called "Z88" uses kinda 20 types of elements (2D and 3D). You can download the manual and read more about these elements, maybe you will find the answer of your question there. This is the direct link to the manual...

Active pressure acting right to left, passive pressure acting left to right. The passive pressure could be considered as spring support.

I would consider FRP too.

For such a thick foundation I usually use 3D elements (solids). In your case it would be 3 layers x 0.40 m or 4 layers x 0.30 m. The XY size of the solids would be adequate (0.30`0.50 m)

According to which code?

In such a situation I would use "Sika Latex" or something similar to provide the adhesion between the "old" and the "new" concrete. Together with dowels of course.

I think that this depends on the horizontal forces applied to the foundation.

I would try to do something like the sketched in the attachment. Would pour additional concrete around and under the free edges of the footing so that the part that's over the elevator pit could be neglected (demolished). The change of the shape in plan is a try to avoid or minimize the change...

No need to change the column dimensions at the hinge side. And where the rigid connection is, I would widen the column locally.

Holo-bolt or self-drilling screw would do the job. The second one is most common in my country. The other option is to design produce something that looks like the part that I showed you and weld it to the steel part.

I would use something like this:http://metamix.bg/drv_files/drv1/wbz_big.jpg

What type of connection do you want to release - rigid or hinge?

I agree with concretemasonry or else I would use something like this:http://us01.webdms.sika.com/fileshow.do?documentID=242

14.1.0 is OLDER than 14.2.4, so probably you will not able to open the file. Or you can try to export the model to another file format...

When you select the joint you will see its all the three coordinates in the status bar (lower left, if I am not wrong).

No need to delete the load case. You can just toggle between (Run/Do not run the case). Just press F5 and select what you want.

Seems quite too late for you, but maybe this will help somebody else: http://www.steelbiz.org/Discovery/AllResults.aspx?q=%22wind%22

Initially read EN 1993-1-1, chapter 5, especially 5.3 and 5.4. Then just follow the track.
