I was performing ground response analysis in PLAXIS 2D with and without considering structure. From analysis, I found PGA in soil-structure integrated model is high as compared to free field analysis, I couldn't find my answer from literature review. Can anyone kindly reveal the reason behind it ? This conclusion is being main point of discussion of my thesis work.
