1. Analysis of Singly reinforced concrete beam. For the beam shown below, determine the following: - 10 ft PL=32 kips WD=2k/ft d=? h=34" (excluding beam weight) 6 #9 bars 20 ft —b=16”. (a) Determine the maximum ultimate moment, Mu. (b) Compute the flexural strength, MR, of the beam using internal couple method. (c) Compute the flexural strength, MR, of the beam using ACI tables method (Using flowchart and appendix tables). (d) Is this beam adequate for the design moment according to ACI Code? (e) If it is over-designed, MR>>Mu, what would you suggest as Structural Engineer to change in section/reinforcing to decrease it? Explain why. (f) Does it satisfy other requirements of ACI Code (minimum required width of the beam to furnish rebars, min. reinforcement ratio)? - |||| - Other properties of the beam: Concrete properties: f'c = 4000 psi and density of 150 pcf. Steel properties: grade 60 steel rebars. Beam is an internal member, Cover=1.5in Assume #3 stirrups are used.
