Question 2: A residential building construction development is using columns that are 4.2m in hieght. The columns are made from seasoned Western Hemlock of Grade F14, with nominal dimensions of 190x45. Intermediate restraints are provided at 1.05m centres to minimize buckling about the minor axis. For the columns under consideration, intermediate restraints for minimizing buckling about the major axis are located at 2.1m centres. The columns can be considered as secondary members as they are closely spaced enabling load sharing. The columns carry unfactored compressive loads as follows: a permanent (dead) load of 50KN, an imposed (live) roof load of 30kN and wind load of 10kN. Assume that the imposed roof load is infrequent in nature (construction related) and that both the long-term imposed (live) load factor (y) and combination factor for imposed action (y) are equal to zero. Location: Rockingham, Western Australia. Check the ability of the column to support the applied loads if the column is restrained at both ends in position and direction.

Given a concrete column that would be required to support loads of Pu=400kips and Mu=50 kip-feet, we will determine the column interaction curve and decide if the column is adequate for this particular application. The column will be a 14”x14” square, tied column with #9 bars at the corners. The center of the reinforcement in each corner is 3” from each of the sides. The f’c of the concrete is 4 ksi and the reinforcement is Grade 60. Determine if the column is acceptable for this application. Calculate the value of Mu and Pu.
