All work must be shown. You are in charge of retrofitting an existing building. The columns and girders are in place, and you have to design the beams. The building is high end (deflection limited to live load limit of L/480 and a dead load+ live load requirement of L/240). Design the most economical beam size (using conservative calculations) if the unfactored live load is 100 psf and the unfactored dead load (including beam weight) is 80 psf 30 Points...

simply supported reinforced concrete beam of rectangular section is hung on the left end by a 400mm square post working in tension, as shown in the figure below. The beam supports a uniform dead load (DL) gf 100 KN/m (excluding its own weight) and upiform live load LL) of 40KN/m. The beam is reinforced with 025 longitudinal rebars with 40mm cleat cover to the stirrups. Material properties: fy 420 MPa, fe 25 MPa. Beam dimension b 400mm and h 600mm....
