Calculate the maximum allowable load (in kN) that a nominal 350mm x 350 mm sawn lumber column, 3.5m long, can carry. The applied loading is for 15-year duration and the wood used is visually graded sawn Yakal (E = 9.78 GPa, Fc = 15.8 MPa). The column is effectively held in position at both ends and is fixed for both ends. Use k = 0.65. Blank 1
Calculate the maximum allowable load (in KN) of a 5.0m long sawn lumber column can carry. The nominal size is 152.4 x 152.4 mm (6”x6”) and the actual size is 139.7mm x 139.7mm (5.5” x 5.5”). The applied loading is for 15-year duration and the wood used is visually graded sawn square Narra (E= 11.721 GPA, Fc = 10.342 MPa). The column is pinned both ends. Consider adjustments for load duration and moisture condition.

A beam will support a combination of dead, live, and earthquake loads. The Load Duration Factor for Dead is 0.9, Live is 1.0, and Earthquake is 1.6. The Dead load causes a stress of 300 psi, the live load causes a stress of 200 psi, and the earthquake causes a stress of 100 psi. The tabulated strength of the wood is 1000 psi. What is the critical (largest) Demand/Capacity ratio for the beam? (Demand/Capacity is fb/Fb'.)
