oversized columns
(OP)
For oversized columns (where it is made larger than needed), can someone confirm that the beams framing into it indeed suffer greater moments during seismic activity?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

RE: oversized columns
Is this a simple house type of structure, or a medium to large building or a bridge or what? What materials are used? What type of connections are used between columns and beams? What are the relative spacings of members relative to each other? All of these things must be considered before even attempting to answer your question.
For non-simple structures.... I generally like to analyze models rather than simply rely on my engineering judgement about such things. I find loads and forces often have a way of doing things other than what you think they are going to do.

RE: oversized columns
Create a simple concrete beam and columns at etabs. Subject it to seismic loading. When you change the size of the columns bigger, the beams framing into it has bigger moments.. so oversize columns can introduce higher moments to the beams?
