In the reading 3 we have learned about the forces that are acting on the buildings. In my opinion this reading was more comprehensive than our previous readings as it had a lot of physics concepts involved which may be difficult to understand when seen these for the first time. Fortunately most of these concepts were familiar to me as I have started as a civil engineering student and I have studied these concepts before. It was a great refresher of these concepts for me as the Francis D.K. Ching was able to explain all these comprehensive subjects in much simpler language than the other books I have seen when I was taking engineering classes. The new concepts that I have learned from this chapter were joints & connections and how domes work. In addition reading chapter 3 from the book and refreshing the forces concepts, helped me to prepare and ace my structure II midterm.
