6.2.1. Approximate Methods

Try these first

1. 1.

   What is a tributary area?

   Hint

   Think about how slabs affect beams.

2. 2.

   What does uniformly distributed load mean?

   Hint

   Consider how weight is distributed on a table.

3. 3.

   What is a tributary area?

   • The area of the beam
   • The area that contributes load to a beam
   • The area on the roof

   Hint

   Think about how load is shared among beams.

4. 4.

   The equivalent load for bending moments is represented by which symbol?

   Hint

   What letter is used to denote equivalent loading for bending?

5. 5.

   A slab of dimensions 50ft by 40ft is supported by beams every 10ft. Calculate the tributary area supported by a beam located at 20ft along one side.

   Hint

   Remember to calculate half the distances on each side of the loaded beam.

6. 6.

   For a beam with a span of 30ft and maximum loading distance of 15ft, calculate α and β. Show all your work.

   Hint

   Plug your values into the respective formulas carefully.
