Test-based Design Method for Steel Cantilever Beams

The main purpose of this research is to perform a large-scale experimental testing program to evaluate the stability response of overhanging cantilevered beams to achieve more reliable, efficient design guidelines and potentially reduce construction costs. This will complement the lateral–torsional buckling testing program currently underway at the University of Alberta, which investigates the stability response of welded steel bridge girders with doubly- and singly-symmetric sections. The experimental investigation will be complemented with extensive numerical simulations. […]

Experimental Validation of Seismically Resilient Concentrically Braced Frames with Replaceable Brace Modules.

This project is part of a multi-year effort to develop a new replaceable brace module for seismically resilient concentrically braced frames. The overall objectives of this design concept are to: (1) replace field welding with field bolting, (2) avoid out-of-plane buckling that can cause dangerous damage, and (3) simplify post-earthquake repairs. In this phase of the study, the aim is to conduct large-scale system-level experimental testing to capture the interaction of the replaceable brace […]

Assessment of Fatigue Design
Provisions for Welded Shear Studs in Steel-Concrete Composite Bridges

The shear connection between steel girders and concrete bridge decks is most common commonly made with welded shear stud connectors, primarily due to its ease of installation. However, the detail is fatigue critical because of the presence of the welds. The fatigue design provisions, which nearly always govern for these studs, have not been significantly updated in over fifty years. The aim of this research will be to establish a new endurance […]

HSS Joint Welding

This research project will clarify options available for the fabrication of welded rectangular Hollow Structural Section (HSS) K-connections, and their implications for design. The aim is to liberalize current constraints applied to: member geometric parameters, the relative positions of branches (with regard to gap size, zero gap, or amount of overlap), miter cutting and required welding. The study will focus on truss K- and N-connections with a wide range of eccentricities, gaps and overlaps, with […]

Performance Based Seismic Design of Innovative Damage Free Rocking Steel Bridge Piers

The objective of this research is to investigate, through experimental and numerical studies, the concept of self-centering mechanism in steel bridge piers. Since any damage to a transportation system could have significant impacts on society and economy, the need for the design and development of new bridge components and systems with damage avoidance mechanisms has been increasingly highlighted over the recent […]

Design of Beams with Overhanging Segments Against Lateral Torsional Buckling

This research is to investigate the lateral torsional buckling of beams with overhanging segments (commonly known as the Gerber girder system).  Such structural elements are quite popular in Canada, and used widely for multi-bay arrangements.  It has the advantages of maintaining a statically determinate system with an effective and economic balance of hogging and sagging bending moments and reduced deflections, while avoiding complex and costly moment connections. Currently there is a lack of clear, practical […]

Analysis of Concentrically Loaded Braced Frame Using Continuous End Plate

The purpose of this research is to examine the behaviour and design of continuous end-plate connections in concentrically braced frames.  This type of connection is not explicitly addressed by the current design standards, thus resulting in designs that are often too conservative. Furthermore, although this connection is usually assumed conceptually to be pinned, the effect of the continuous end plate may qualify this type of connection as semi-rigid resulting in an actual load-resisting system behaviour […]

Simplified Design Methods for Steel Multi-Tiered Braced Frames in Regions of Low and Moderate Seismicity

Steel multi-tiered braced frames are commonly used in tall single-storey buildings such as airplane hangars, sports facilities or industrial plants to provide lateral bracing when it becomes impractical to use braces that extend the full storey height. Although the multi-tiered configuration offers significant advantages in high seismic areas, it is also the most common […]

Promoting Steel as a Material of Choice in Bridge Infrastrucutres: Current and Future Innovations

With increased prices of steel, bridge owners and design engineers have become more reluctant to using steel in bridge superstructure, as it may be cost prohibitive. In this research, some countermeasures and innovative techniques are proposed that can be considered to (i) reduce the steel material content in bridge superstructure; (ii) enhance the constructability of steel I-girder and box-girder bridge systems in both straight and curved alignments, leading to a significant cost saving; […]

Hot-Dip Galvanized Hollow Structural Sections – Crack Prevention and Mechanical Behaviour

The application of hot-dip galvanized cold-formed Hollow Structural Sections (HSS) in exposed steel structures (e.g. bridges, transmission towers and sign supporting structures) is extremely popular due to their superior strength-to-weight ratio, low initial cost, sustainability and aesthetics. Both HSS manufacturing and hot-dip galvanizing techniques have evolved over the years. However, the use of newly developed zinc bath mixtures together with thick-walled HSS resulting in significant damage in the latter in the form of cracking during […]

Performance Based Seismic Design of Steel Bridges According to CHBDC S6-14

The latest release of the Canadian Highway Bridge Design Code S6-14 incorporates for the first time Performance Based Seismic Design (PBD) provisions for bridges in Canada. As this is a significant departure from the traditional Force-based design approach, practicing engineers are facing a number of challenges associated with the implementation of PBD for seismic design of bridges. Although the decision to incorporate PBD requirements on the bridge code […]

Completing the Load Path for Controlled Rocking Steel Braced Frames

The aim of this research is to develop and validate feasible connection details between floor diaphragms and Controlled Rocking Steel Braced Frames (CRSBFs). Connection details will be designed to achieve desired performance criteria while also minimizing costs associated with construction and fabrication, and the proposed connections will be tested experimentally under cyclic loading. The laboratory results will be used to validate the finite element models that were used to design the connections, and to develop simplified design […]

Development of Innovative Steel Diagrid High-Rise Structures for Seismic Applications

This research aims to create an innovative steel diagrid structure for high-rise building applications in areas of high seismicity. This system utilizes the high stiffness and strength of steel to create a diagonally integrated mega steel grid structure that can transfer lateral loads to the foundation efficiently and effectively. The combination of the mega steel grid system with the gravity system allows the designers to create new architectural flexibility, achieving new buildings heights and shapes […]
