Design a rectangular beam to carry a live load of 1.5 kips/ft and a dead load of 1.5 kips/ft inn addition to the beam weight for a simple span of 32 ft use an approximate steel ratio P of about 0.375 of the balanced amount and also satisfy aci table 9.5 use fc' 4000 psi fy 40.000 psi and dy=60.000 psi

5. The beam-column has a height of 7.5m and is a member of a braced frame. It is subjected to an axial load of DL-65KN and LL= 1OOKN. It is pinned at both ends. A W12X35 section was used and was made up of A-36 steel with Fy-250MPA. Compute the interaction value for beam- column based on NSCP 2015 code provisions. Ngelect the weight of the section.
