Problem 3: A simply supported wooden beam, 12' long, is acted on by P= 10 kip at the mid-span and a uniformly distributed load w = 1.5 kip/feet over the entire length. The nominal size of beam cross-section is 8 x 12, however, actual cross-section is 7.5 x 11.5. Calculate the maximum tensile & compressive bending stresses at the top and bottom fibers of the section. ANS: Maximum tensile & compressive stresses (o) are = . -

A simply supported beam as shown in the figure. The beam section is W18x211. The beam must support its own weight and must carry the following loading: Super-imposed distributed dead load = 0.25 kip/ft Distributed live load = 1 kip/ft Concentrated dead load = 12 kip The beam span L = 26 ft and the distance of the concentrated load from the right support a=6 ft. Consider analy- sis of beam subjected to load combination 1.2 dead + 1.6 live....
