Question: A redwood timber member having a 16-in.-square cross section is reinforced with an ASTM A36 structural steel angle ( L5×5× 1 2 ) at each corner, as shown. The materials are so attached as to act as a single unit. Compute the total allowable axial compressive load that may be applied through a rigid cap plate that covers the entire crosssectional area. Use dressed dimensions and assume the materials have the same length. The allowable compressive stress for the steel is 20,000 psi.
