An Isolated Interior Column Which Supports A Second Storey Dining Room For A Restaurant In Duncraig Perth Will Be Made 1 (55.03 KiB) Viewed 39 times

An isolated interior column which supports a second storey dining room for a restaurant in Duncraig (Perth) will be made by nailing two pieces of 35 mm thick MGP12 timber to give a total column thickness of 70 mm. The column height will be 2.8 m and, because it is an isolated column, no bracing will be possible in either direction. In this case gi3 can be taken as 0.9. Unfactored design loads are as follows: • Permanent action 2.76 KN (compression) • Imposed action (crowd-5 days) 11 kN (compression) i. Find strength limit state load combinations representing: • Permanent action plus an estimate of the longer-term imposed action, and • Permanent action plus crowd imposed action. ii. Select the critical load combination for design. ii. Evaluate op factor and all k factors that can be found independent of the member size. iv. Select a member size to be used to make the column from two pieces of timber nailed side by side. V. Check assumptions made in the design and the final capacity.
