Introduction

 

Criteria

1. bending (including lateral stability)
2. shear
3. deflection
4. bearing

 

1-3 depend on beam
4 depends on beam & supports

 

Bending usually controls

1. use bending to estimate beam size
2. check shear, deflection, bearing
3. revise size if necessary

 

Software can be efficient, but LOTS of output is needed (for manual checks).
