Homework Answers
Both the structure is same in nature except for the fact that left structure is having fixed support in left most column while right one has hinged support in place of that. So we have to compare horizontal displacement of both the frames based on this. We know that fixed support has zero slope at support and hence it will offer resistance while displacing frame horizontally due to load P and as such there is no resistance in right frame having hinge end of column hence right frame will have more displacement at C.
