If you have been living under a rock for the last year, you will be shocked to hear that the environment and, more specifically, greenhouse gas emissions is front and centre. For most governments and for the Millenials and post-Millenials, reducing carbon other green house gasses is priority number one. For some industries and some governments, [...]
Reassessing Lateral-torsional Buckling Capacity of Modern Welded Steel Girders Dimple Ji, Robert G. Driver, Ali Imanpour Lateral-torsional buckling is a potential failure mode of steel girders. Under flexural bending, it involves the vertical movement, then simultaneous horizontal sway and rotation of a girder within an unbraced span. Visually, this results in a girder with a twisted [...]
Walk the Cloudraker Skybridge and the Raven’s Eye Cliff Walk and take in the breathtaking views from Whistler Peak. From the Roundhouse Lodge, walk the Peak Express Traverse to the Peak Express Chair; the suspension bridge is located at the Top of the World Summit. The Cloudraker Skybridge spans 420’-0” from Whistler Peak to the West [...]
Recently completed by CISC member Vixman Construction Ltd. for Pomerleau Construction (Giffels), the Sheridan College Engineering building at the Davis Campus in Brampton is an example of creativity in design and construction using multiple types and finishes of steel. The design and construction collaboration between Vixman, the Pomerleau (Giffels) construction team and architect George Friedman resulted [...]
On Monday November 18, 2019, CISC Manitoba/ NW Ontario and Red River College hosted a seminar on structural steel, possibilities, challenges and solutions from an industry perspective. The event gave an opportunity to all 3 years of the college’s Civil Engineering Technology; Architecture and Construction courses and interested others to hear 1st hand how a [...]

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 [...]
Wednesday, November 13th, 2019 On Monday, November 11th, the Canadian Institute of Steel Construction (CISC-ICCA) of the Quebec Region celebrated the 21st anniversary of the Steel Awards for Excellence in Steel Construction, at one of the most historic venues in Canada, the prestigious Montreal 'The Windsor', offering a welcome cocktail, a gourmet 3-course dinner, in a [...]
"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, [...]
