Beam Design

          The design of wood beams is similar to the design procedure for beams made of other structural materials.  There are four limit states that must be considered when designing a wood beam.

1.  Bending

2.  Shear

3.  Deflection
4.  Bearing

          Bearing capacity is used to determine the required bearing length at the supports of the beam.  This module will focus on design for bending, shear, and deflection, all of which may govern the size of a wood member. 

 

Note: Table 5.2-1 in the 1996 LRFD is incorrect.  A copy of the corrected table can be found here.
