What do you mean by eccentricity of gravity loads? At the level where I am getting the large shears, the diaphragm is smaller (it steps in), which changes center of mass relative to center of rigidity. Is that what could be causing it? I don't have stepped foundations. I do have footings under each column, but they are place holders and have not been designed yet.

Eccentricity of gravity loads, or something tipping the structure to one side like a stepped foundation, soft support, etc. Check the deflected shape for a better understanding.
