Which of the following is the leading cause of Unintentional Injury death in the United States? 

If a building contains columns that are evenly spaced every 17 feet in the north-south direction and 24 feet in the east-west direction, the tributary area of a typical corner column would be _______.

Find the reduced roof live load for a one-story building which has columns evenly spaced every 16 feet in the north-south direction and 20 feet in the east-west direction. The building has an ordinary pitched roof with a slope of 3 inch/foot.

The two columns in the following floor framing plan support only loads from a theater with fixed seats on the second floor. The city has approved floor live load reductions for this particular building. A dead load of 12.7 psf acts on the tributary area of the columns. Combine this with the reduced floor live load, and then determine the total load that acts on one of the columns.
