I was wondering if anyone could help explain how the Vertical reactions for the following structure were calculated.
I am able to calculate the Horizontal reactions. It is the vertical reactions that I am struggling with.
I do the following:-
Sum Vertical Reactions = 0
Va + Vd - 230 = 0
If I take moments about D I get:-
Sum of Moments about Support D = 0
(5.4*230) + (Ha*1.8) = 0
Ha = -690kN
I just don't know how to calculate 230kN at support A.
