The Leaf is a newly constructed building and the centrepiece of Canada’s Diversity Gardens at Assiniboine Park in Winnipeg. This 6000+ square-metre facility features four distinct zones that transport visitors through a suite of different biomes and environments. While featuring several elevated design elements, one of the most prominent features of the structure is its ETFE cable net roof that tensions off the 33-metre-tall steel diagrid tower. Rising from the centre of the structure, this diagrid tower includes architecturally exposed 324mm OD HSS/Pipe members with 6-armed, multiaxial custom-designed cast steel nodes. A propped walkway, supported on tubular steel struts complete with standardized cast steel connectors, emerges from the tower, allowing visitors to take a stroll around the 6-story tall indoor waterfall and explore the space from above.

In this presentation, explore how the design team leveraged a cast node design realization study to target the desired aesthetics of the diagrid tower. Learn how the design team used the free-form capabilities of castings to create the overall geometric form while improving the structural efficiency of HSS-to-HSS connections. Identify how precision-machined steel castings simplified fabrication and facilitated constructability and explain how the use of steel castings promoted the economy of the overall structure.

This presentation will highlight how to use the handbook to address some common design problems and frequently asked questions that we receive here at CISC.

To make the right and optimum design choices you need to understand the premises of your decisions. Understand why and how to make the right material comparisons. Facts matter!

Steel-framed parking structures (SFPS) built today are radically different from their predecessors. Innovative techniques have revolutionized the corrosion-resisting capabilities of structural steel and have satisfied corrosion concerns. It’s time to consider SFPS as viable and superior parking structure to the current norm in Canada as they provide a platform for aesthetic expression that lasts for decades. A SFPS will improve the return on your investment through benefits in significant savings in project cost and schedule. During the presentation we will discuss the many benefits of a SFPS as well as the structural and architectural considerations that must be made to make for a successful project.

This 1-hour presentation attempts to de-mystify HSS connections. While this is not a “how-to” guide, the presentation will highlight areas of HSS connection design that are often overlooked or misunderstood. Connection types that are addressed include tension, bracing, shear, moment, and truss connections. Attendees will gain an appreciation of the similarities and the subtle differences between HSS connections and other types of connections. Also addressed will be the effect certain design decisions have on fabrication and the cost of connections.

Buddy Holly Hall in Lubbock, Texas, was completed in 2021 and has fulfilled the aim of creating a hub for the arts and culture community as well as a venue capable of attracting top talent for world-class performing arts events. Designed by a Canadian team in collaboration with local partners, structural steel contributes to the architectural expression throughout the Hall. This session will trace the project development and explore innovative steel solutions to bring this unique project to life: from the monumental stair in the main lobby to the horseshoe shaped balconies in the 2297-seat main theatre and beyond.

‘Coreless steel modular’ being steel-framed modular buildings that use steel as a lateral force resisting system (with or without supplementary damping or base isolation). The current approach is to use a cast in-place reinforced concrete core for these buildings.

There would be discussion on low and high seismic zones.

Les structures de stationnement à charpente d’acier modernes sont radicalement différentes de leurs prédécesseurs. En effet, des techniques novatrices ont révolutionné les capacités de résistance à la corrosion de l’acier de charpente, réglant du coup les problèmes à ce sujet. Le temps est venu de considérer ces structures comme une solution viable et supérieure à la norme acceptable au Canada puisqu’elles offrent une plateforme élégante qui dure des décennies. Une structure de stationnement à charpente d’acier améliorera le rendement de votre investissement grâce à des économies importantes sur le coût et le calendrier du projet. Durant la présentation, nous discuterons des nombreux avantages d’une structure de stationnement à charpente d’acier ainsi que des considérations structurelles et architecturales qui doivent être prises en compte pour assurer la réussite d’un projet.
