Section 2.4.2

Example Problem 2.2

Last Revised: 11/04/2014

Given:  The beam diagram in example problem 2.1

Wanted:  Draw the beam load diagrams for the following load combination equations:

LRFD ASD
LRFD LC2 ASD LC2
LRFD LC4 ASD LC5
LRFD LC5  

Solution:  This is the same problem as example problem 2.1 except we are looking at a few more load combinations.  Click on this link to see the solution.  This spreadsheet solution shows most of the steps in each calculation and contains some commentary about the resulting beam diagrams.  Take some time now to examine this solution thoroughly.  We have included some ASD load combinations in this example.  Take note of the discussions embedding in the solutions about eliminating load combinations by observation.
