Timber & Masonry Design

What you'll learn

• Explain how the structure, grading and moisture content of wood determine its properties, and apply the CSA O86 modification factors for load duration, service condition, system and size effects.
• Design sawn lumber joists and glulam beams for bending, shear, bearing, deflection, creep and lateral stability, and recognize when stiffness governs.
• Design timber columns for buckling and timber members for combined bending and axial load, including effective lengths about each axis.
• Design cross-laminated timber panels with effective stiffness and shear deflection, and calculate the fire resistance of glulam and CLT members from char depth and the residual section.
• Design bolted, nailed and screwed wood connections with the yield model, accounting for the angle of load to grain, spacing and edge distances, group effects and splitting.
• Design wood-frame diaphragms and shear walls for wind, including unit shears, chord forces, nail spacing and hold-down forces, in the O86 format.
• Select masonry units, mortar and grout, compute section properties of hollow and grouted walls, and establish the specified compressive strength from the S304 tables or prism tests.
• Design unreinforced and reinforced masonry walls for out-of-plane bending, including the effective compression width of partially grouted walls and reinforcement limits.
• Design loadbearing masonry walls for axial load, eccentricity, wind and second-order P-delta effects with cracked and uncracked stiffness.
• Design reinforced masonry shear walls for in-plane shear and flexure, and explain how ductility, stiffness and minimum reinforcement govern lateral systems.
• Lay out control and expansion joints and detail masonry veneers, ties, flashing and weeps for movement, water management and cold-climate durability.
• Assemble and review a design package for timber and masonry buildings, including the design basis, member schedule, missing load cases, drawings and construction quality assurance.
