Punching Shear in Spread Footings to CSA A23.3
Size a spread footing for punching shear to CSA A23.3-24: the size effect factor, the 2d footing exemption, the depth quadratic and a one-way check.

Tension Development Length - Decoding the K-Factors in CSA A23.3
CSA A23.3-24 renamed the K-factors and added a grade factor, so a 25M top bar in 500W steel needs 1501 mm, 39 % more than in 400W. See which factors move.

A Practical Guide to Flexural Design of Reinforced Masonry Beams to CSA S304-24
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.

When Standard Hooks Are Your Only Option
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.

Arching Action Over Openings: What a Masonry Lintel Really Carries
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.

Bolt Shear and Tension Resistance to CSA S16-19
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.
About Me
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.
