Use the previous information and image for questions that follow. Design the upper left corner column (A-1) at the ground floor level, assuming that the building has 4 floors. Would a W12x22 section be appropriate for this column and why? If not, suggest a section that support this load safely. Show all calculations. Assume: The column height is 15', non-braced, but it is "fixed" at the bottom and "pinned" at the top. Use the previous information and image for questions that follow.
