A 200 foot tall building has columns with a cross sectional area of 10 square inches made of steel (E=29,000 ksi, = 6.45x10-6 in/in/°F). The average load on the column is 300 kips. For these conditions find the following: a. the total column deformation b. the average axial stress c. the deformation in the column caused by a temperature increase of 50°F. d. If the temperature changes as noted in question C, will the average axial stress of question b change? Why?
