For all problems, use concrete compressive strength $f_c=35$MPa, No$.10$ stirrups, and concrete

cover of $40mm.$ Use the same concrete unit weight given in the problem statement. Do not use

the reinforcement ratios given, instead, calculate your own. For each problem, show sketches of

cross sections including bar sizes, arrangements, and spacing.
