Learning Goal: I’m working on a civil engineering discussion question and need the explanation and answer to help me learn.
Design an interior square column for the ground floor of a threestory building. The connection of the ground floor column to thefoundation is considered to be pinned. The columns are not bracedagainst sidesway and are bending in a single curvature. The loadsacting on the first-floor interior column due to gravity and wind areas follows:P dead load = 380kP live load = 140kP wind load = 0M dead load = 32 k-ft (top) and 54 k-ft (bottom)M live load = 20 k-ft (top) and 36 k-ft (bottom)M wind load = 50 k-ft (top) and 50 k-ft (bottom)All columns are 21×21, all beams are 16×24.Use fC=4,000 psi, fy=60,000 psi.
