CISC Design Modules – Module 3
Gerber Roof Girders The third module in CISC's Design Modules lineup, "Gerber Roof Girders " has been published and is now available. The first two modules on "Eccentrically Loaded Bolt [...]
Beams with Web Holes
Building structures are designed to support a variety of pipes, ducts, conduits and other services. Efforts to reduce floor heights have led to these items being placed in the [...]
HSS Produced to ASTM A1085
ASTM A1085/A1085M, Standard Specification for Cold-Formed Welded Carbon Steel Hollow Structural Sections (HSS), was introduced in 2013 and was listed in CSA S16 Clause 5.1.3 for the first time in [...]
Matching and Non-Matching Welding Electrodes
Welded connections in structural applications are normally designed with matching electrodes, as listed in Table 4 of CSA Standard S16 for steels produced to CSA G40.21, "Structural Quality Steel". Starting [...]
Seismic Corner: When Other Loads Govern
For practicality and economic reasons, codes are reluctant to enforce design for full elastic forces, especially where seismic forces are large. Inelastic design complicates the design substantially and has led [...]
