You are analyzing a 40 FT long simply supported beam (b = 10 IN, d = 21.5 IN, h = 24 IN) in an existing building. The dead load on this beam is 1.2 KLF and you are tasked with deciding whether a load of 2 KLF of live load can be applied in addition. Based on the original plans, you think that the compressive strength of the concrete f’c = 3000 PSI and the yield strength of the rebar is 40 KSI. The existing stirrups are #3 bars (2 legs) at 9” centers along the entire beam.
