Question
A W14 × 34 standard steel section is used for a simple span of 13 ft 6 in.  Determine the maximum uniform load that it can support if the allowable bending stress is 32 ksi and the allowable shear stress is 18 ksi.  Assume bending about the strong axis of the W shape.

Part 1

 
Use Appendix B to look up the dimensions of the cross-section and the area moment of inertia. Then determine the maximum allowable internal bending moment so as not to exceed the allowable bending stress.

M =       kip·ft
 
 
 

Part 2

 
The maximum shear stress will occur at the neutral axis. Draw a horizontal line through the centroid and calculate the maximum first moment of area for the cross-section.

Answer:

Q =        in.3
 
 

Part 3

Determine the maximum allowable internal shear force so as not to exceed the allowable shear stress.

V =       kip
 
 
 
 
 

Part 4

 
 
Sketch the shear force and bending moment diagrams, and determine the maximum shear force and bending moment in terms of the distributed load w. Then calculate the magnitude of the maximum value of w so as to not exceed your maximum allowable shear force.

Answer:

w = kips/ft
