Robert Tremblay is Professor of Structural Engineering and former Canada Research Chair in Earthquake Engineering at Polytechnique Montreal, Canada. Before undertaking his doctoral studies, Prof. Tremblay worked for 10 years in the industry. His current research activities are mainly directed towards the seismic design and response of steel structures for buildings and bridges, with focus on innovative structural systems for enhanced seismic performance. He is a member of the CSA-S16 Technical Committee on Structural Steel Design (Chair of the Work Group on Seismic Design), Standing Committee on Earthquake Design of the National Building Code of Canada, CSA-S6 Sub-Committee on Seismic Design of Bridge Structures, AISC Task Committee 9 on Seismic Design Provisions for Structural Steel Buildings, AISC Task Group on Industrial Buildings and Nonbuilding Structures, and the AISC Adhoc Task Group on Seismic Analysis 2020.
In Canada, the use of bolted connections are generally preferred for steel concentric X-bracing diagonals made of HSS profiles or double angles back-to-back. Experimental and numerical studies conducted at Polytechnique Montreal have shown that these connections are likely to buckle in compression and undergo a complete tensile rupture under the effect of a seismic event. The expected failure modes will be presented and discussed. Calculation methods will then be presented to predict the buckling strength of the connections in order to obtain adequate seismic behavior.
