Engineers’ Corner: Braced Frames for Low to Moderate Seismicity

Braced Frames for Low to Moderate Seismicity, published by the CISC, illustrates the design of seismic force-resisting systems (SFRS) and brace-to-gusset connections for concentrically braced frames in areas of low to moderate seismicity (See Figure 1). The design notes refer extensively to the National Building Code of Canada 2015 (NBC 2015) and to CSA S16-14, Design [...]

Engineers’ Corner: Fillet Weld Resistance in CSA S16:19

CSA S16:19, Design of steel structures, has introduced changes to the factored shear resistance of fillet welds. In both the current edition, S16:19, and the previous one, S16-14, the shear resistance of a concentrically loaded weld segment is given in Clause where: If we incorporate the strength enhancement factor and the reduction factor for multi-orientation [...]

Engineers’ Corner: Maximum Unbraced Length of a Beam

A quantity that is often used when designing a steel beam according to CSA Standard S16 Clause 13.6 is Lu , the longest unbraced length with which the beam will reach either Mr = φ Mp or Mr = φ My , depending on the class of the cross-section. In other words, whenever the unsupported length of a [...]
