1. For the frame loaded as shown, determine the following using ACI 318-14, f'c=28 Mpa, fy=414 Mpa for main bars, and fy=276 Mpa for secondary bars:
a.) the positive and negative reinforcements of the beam
b.) the required percentage of column reinforcements using the ACI interaction diagrams and the recommended bars using the NSCP-2015 Standard
c.) the critical spacing of stirrups for the beam
d.) the recommended spacing of column ties considering column shear only.
