PROBLEM 1: The beam shown is made up of W 24 x 55 structural steel. It carries an unfactored uniform service dead load of 12.52 KN/m excluding its own weight and an unfactored uniform service live load of 4.15 KN/m. It also carries an unfactored concentrated service dead load of 6.67 KN and an unfactored concentrated live load of 7.84 KN both at its free end. The cantilever beam has a length of 1.56 m. Use A-36 steel and LRFD.

Topic: structural steel beams

PROBLEM 1: The beam shown is made up of W 24 x 55 structural steel. It carries an
unfactored uniform service dead load of 12.52 KN/m excluding its own weight and an
unfactored uniform service live load of 4.15 KN/m. It also carries an unfactored concentrated
service dead load of 6.67 KN and an unfactored concentrated live load of 7.84 KN both at its
free end. The cantilever beam has a length of 1.56 m. Use A-36 steel and LRFD.
Question:
1. What is the unfactored weight of the beam itself in KN/m ?
2. What is the total factored uniformly distributed dead load of the beam in KN/m. ?
3. What is the total factored uniformly distributed load of the beam in KN/m. ?
4. What is the total factored concentrated load of the beam at the free end in KN?
5. What is the actual maximum external shear of the bear in KN?
6. What is the actual maximum external bending moment of the beam in KN-m.?
7. What is the moment capacity of the beam in KN-m.?
8. What is area of the flanges in mm?
