The following rules apply to signs:
-
Downward displacement w [m] positive.
-
Rotation phi(x) [radians1] = rotation around the x-axis is positive clockwise (direction of view for increasing values of x)
-
Rotation phi(y) = rotation around the y-axis is positive clockwise (direction of view for increasing values of y)
-
Point load P [kN] positive downwards
-
Moment mxx = moment generating stresses in x-direction, positive clockwise (direction of view for increasing values of y)
-
Moment myy = moment generating stresses in y-direction, positive clockwise (direction of view for increasing values of x)
-
1 Radians: For example, a value of 0.02 means 0.02 · 180/ = 1.15°
