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.

Solutions

Expert Solution

it is required to analyze the shear capacity of section and compare it with factored shear due to given loading

it is assumed that beam have sufficent capacity in flexture

section capacity is not sufficent to carry 2 klf live load
