Design a reinforced masonry beam for flexure to CSA S304-24: grouted f'm, the balanced limit as rho_b and K_b, course depths and an 85 kNm lintel worked out.

CSA A23.3-24 rewrote the hooked bar equation: a 25M hook at 30 MPa grows from 460 to 721 mm. See how the cover and tie factors win the length back.
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.
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.
