The sixth entry in CISC's Design Modules lineup is now available on Amazon.ca. The new 148-page publication is intended to accompany the CISC course on Industrial Building Design. Design Module 6, Industrial Steel Structures, illustrates the design of a typical mill building carrying two 40-tonne cranes. The example frame featured in the course consists of [...]

Prefabricated prefinished volumetric construction (PPVC), sometimes referred to simply as modular construction, is a process whereby buildings are planned and designed to allow for discretization and standardization of 3D volumetric structural units that allow for efficient off-site manufacture and rapid on-site assembly. By Tom Greenough and Matthew Smith Introduction The fabrication and manufacture process results [...]
"Straight Steel Girder Bridges", illustrates the design of composite, continuous multi-span steel bridges following a straight roadway alignment. This module includes detailed calculations of a 3-span plate girder bridge (see Figure 1) and a 2-span box girder bridge (Figure 2). Structural design aspects covered in the examples include section properties, slab reinforcement, slab casting sequence, [...]
For hollow structural section (HSS) connections, welds can be designed either to achieve the capacity of the connected branch member wall or to be “fit for purpose” (i.e. to resist the forces present in the branch member). The latter approach typically results in smaller, more economical welds, but it requires the use of weld effective properties. [...]

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 same plane as the structural floor members. Structural systems using trusses and open-web steel joists provide openings for structural/mechanical integration. However, when beams with solid webs [...]
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 the 2014 edition. Figure 1 Hollow Structural Sections Wall thickness and mass tolerances for A1085 products are essentially the same as those specified for HSS [...]
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 with the 2014 edition, the S16 Standard now permits the use of non-matching electrodes with reference to CSA W59, "Welded Steel Construction - Metal Arc Welding", [...]
