For the cross section shown below, the material and sectional properties are given as follows: A) Determine the maximum steel area A_s that can lead to tension driven failure. One can use Table A.4 in the textbook to easily calculate design parameters. B) To ensure under-reinforcement, the steel area is to be decided as a value between 90% and 95% of estimated in P1(a). Determine the reinforcing bars (i.e., bar size, and the number of bars) to meet the required steel area. It is assumed that a single type of rebar is chosen (i.e., rebars of different sizes shall not be combined). C) Given the decided steel area, calculate the nominal and the design moment capacity. One cannot use the design aids.
