6.2. Tributary Areas for beams and columns

Try these first

1. 1.

   Define tributary area in relation to beams.

   Hint

   Think about what supports the beam.

2. 2.

   What distinguishes an interior column from a corner column?

   Hint

   Where is the column located?

3. 3.

   What is a tributary area?

   • Area supported by a beam
   • Area outside a column
   • Area of a foundation

   Hint

   Relate to what directly supports the beam.

4. 4.

   True or False: The tributary area for an interior column is the same as a corner column.

   • True
   • False

   Hint

   Think about column positions.

5. 5.

   Calculate the total load on an interior column supporting four beams when each beam bears an equal load of 10 kN and the tributary area is four times that of each corner column.

   Hint

   Focus on cumulative load effect from multiple beams.

6. 6.

   Given a rectangular slab of dimensions 25 ft by 15 ft with beams placed at equal intervals, compute the tributary area for an edge beam and discuss the load distribution format.

   Hint

   Visualize the positioning and how each section shares its load.
