Question

df Assigned: 20 February 2018 Due: 01 March 2018 1. For the rectangular cross section shown compute the nominal (M,) and design flexural strength (OM.) using the different reinforcement ratios corresponding to a net tensile strain of 0.002, 0.0025, 0.0030, 0.0035, 0.004, 0.0045, 0.005. Use f, = 60,000 psi and f', = 4,000 psi. Using these data points, plot M, and OM, as a function of reinforcement ratio and comment on your results. (Note: I suggest using a spreadsheet for calculations and plotting) Discuss your results, particularly focusing on the penalty paid for having sections with higher reinforcement ratios (higher than those allowed by ACI 318).
