I appreciate the reply.
I don't quite follow.
Firstly, you say that member AH and DE are load bearing walls. Are members BG and CF not load bearing? Why, why not?
Member BG receives load from its tributary area. This load is a distributed load on member BG that can be calculated as a singular load by multiplying with the length of member BG. Dividing this singular force by two we get the support-reactions at B and G which are shown in figure (b) of the the solution. So the reactions are shown in figure (b) but not in figure (c). What is the reason for this? I mean, is there any technical reason for this?
I greatly appreciate the feedback.
