I am designing a three-storey residential building where its rear side (at both corners) sit nearly on the property lines. A friend suggests using 'tie(ground) beams' connecting all the moment resisting frames. According to him, that way the moments both from seismic and gravity loads will be carried by the tie beams. Thus no moments are transferred down to footings and settlement are equal. Finally we can design those eccentric footings only for axial loads.
I am not sure if you are convinced with it. I need your advice and any helpful reference.
Thanks so much!
