Question:
A concentrated load P is acting at the center of the beam having a simple span of 9m. The W14 x 120 beam is made up of a wide flange with yield strength of 345 MPa and a Modulus of Elasticity of 200 GPa.
Properties of W14 x 120:
w = 1.757 kN/m
d = 367.8 mm
bf = 372.6 mm
tw = 15 mm
tf = 23.9 mm rt = 102.62 mm
Sx = 3123.4 x 103 mm3
Based on the condition of support indicated below, determine the following:
a) Is the beam Laterally Supported or Unsupported? Prove your answer;
b) The allowable bending stress, Fb;
c) The max. value of the load P if bending governs. Consider the weight of the beam in the analysis.
1. When the beam is laterally supported only at every 3m distance.
2. When the beam is laterally supported only at every 4.5m distance.
3. When the beam is laterally supported only at every end support.
