Question
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 inmposed (live) load factor (y) and combination factor for imposed action (W) 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.
