Size a masonry lintel with arching: the 45 degree triangle, the 203 mm rule, and why the CSA S304 point load spread moves the moment more than arching does.

Calculate bolt shear, bearing, tear-out and tension resistance to CSA S16-19 Cl. 13.12, with a per-bolt table and a worked four-bolt lap splice.
Size shear friction dowels to CSA A23.3-24 Cl. 11.5: pick c and mu for your joint, solve for the steel, and see what roughening saves at a slab-to-wall joint.
Why concrete creep can triple long-term deflections and what that means for high-rise schedules, form stripping and serviceability.
Why managing errors is the mark of skilled RC design in Canada. Understand CSA A23.3 safety factors, phi values, and construction tolerances.
Transform nonlinear P-Y curves from geotechnical reports into usable spring stiffness values for your structural analysis using secant and piecewise methods.
Why Ie/Ig ratios for concrete walls range from 0.25 to 0.8 across codes, and how to pick the right stiffness reduction factor for seismic analysis.
I’m a structural engineer at Associated Engineering in Vancouver. The work is civic infrastructure: water and wastewater structures, seismic design, and the analysis and drawings that go with them, on projects across Canada and the U.S.
