The loads for a 40’ simply-supported beam are as follows: • Dead Load, D = 600 plf • Live Load, L = 1000 plf Two load combinations need to be considered: a. 1.4D b. 1.2D + 1.6L Given these two load combinations, what is the maximum reaction to be used for the design of the member for strength, assuming the beam is simply-supported? What load (i.e., load combination) should be used to check the maximum service deflection?
