Before you come to class

Now that we have selected beams based on flexural strength, we need to understand how to address other items important for beam design. The content for this week will help you understand how to apply reference design values to check shear strength, deflection, and bearing designs. These lectures will help you use the adjusted design values for beam design. We will work through a couple of example problems before you try it on your own. This module will complete our discussion of beam design.

Questions to think about ...

What is the stress distribution within a wood beam due to shear and how do we use this distribution to determine shear strength?
How do we account for deflection of wood beam elements?
What are important considerations for bearing design at supports and applied concentrated loads?
