Load Determination Homework

Problem 1: Self Weight

Given a simply supported beam has a cross section of 7" by 49".
Determine:

• The TOTAL weight of the beam
• The distributed load of the beam as represented on a FBD

If the beam were made of:

1. Solid Concrete
2. Solid Live Oak
3. Solid Douglas Fir
4. Solid Mild Steel
5. Solid Granite
   

   ---

Problem 2: Distributed Load

Given a simply supported beam must support a walkway. The walkway consists of prefabricated concrete elements that are essentially slabs with a thickness of 5.5" and a width of 3 feet. The steel beam weighs 76#/ft.

1. Draw a complete FBD of the steel beam.
2. Determine the reactions at the supports.

Problem 3: Distributed Loads

Determine the total dead load on a typical foundation of your case study structure.
