Wooden boards - im getting crazy...
(OP)
How do you guys design this?
Lets say we have wooden boards - no spacing between them,
Single board dimensions are: b/h = 200/50 mm


Area load is: q = 3,00 kN/m2
That means that a load per single wooden board is: q' = q x e = 3,00 kN/m2 x 0,20 m = 0,60 kN/m
where e is a distance from center to center of boards.
In model 1 I have area/surface model with an area load and in model 2 i have a simply supported beam (a single board)
Why do i get different bending moments/shear forces...
model 1: Moments = 1,51 kNm/m x 0,20 m = 0,30 kNm is the same as model 2
model 1: Shear = 4,79 kN/m x 0,20 m = 0,96 kN is NOT the same as model 1 (0,60 kN)
Im getting crazy since im working 10 hours straight...

M = wl2/8 = 3(2)2/8 = 1.5 kNm (not 1.51 kNm)
V = wl/2 = 3*2/2 = 3 kN (not 4.79 kN)
For a 200mm wide board, the values would be 20% of the above provided the boards are fastened together with tongue and groove joints or other means of ensuring that the load is spread over several boards. If the boards are not fastened together, it is possible to overload one board with a concentrated load falling within its width.
