Tributary Area Of Slab On Beam. - General Discussion - Structural ... As I understand it, if I was building a simple deck with one side connected to a ledger, the tributary load width would just be half the distance from the ledger to the beam on the other side. Calculate and show Tributary width and tributary area for each assigned beam 3. member supporting that area, ex. Point(PLF) is multiplied by the tributary width to arrive at a Point(lb) load on the member. Depending position of the columns, the area to be considered in the calculation varies. Tributary Areas.
