Simple Span, Uniform Loading, By Load Type, Expanded Deflection Description

At first blush, this example will not look much different from the previous one.  Member loading is still broken down by type and deflection is calculated.  But I have added one line at the bottom of the page to tell me where the maximum deflection occurs.  Where did these values come from?

Scroll to the right past column line "J" and you can see how we arrive at each of the values.  The member span is broken up into short segments and the deflection at each of the segments is calculated.  A maximum deflection is found using the MAX(range) function.  The location of the maximum deflection is labeled and its distance from the left support is noted.

Note also how the total load deflection at any point along the length is simply the sum of the dead and live load deflections at those points.

Breaking the member down into segments will let us work with non-uniform loads (point loads) as we will see in the next example.
