Question: 16.3

## Knowing that column AB (Fig. 16.25) has an effective length of 14 ft, and that it must safely carry a 32-kip load, design the column using a square glued laminated cross section. The adjusted modulus of elasticity for the wood is E = 800 × 10³ psi, and the adjusted allowable stress for compression ...

We note that c = 0.90 for glued laminated wood col...
Question: 16.2
