Demonstration of full-scale earthquake testing of a new seismic protection system

November 17, 2010

TORONTO, ON – University of Toronto Engineering has developed a novel, high-performance steel-cast Yielding Brace System (YBS) for the design of new buildings and the retrofit of older ones, to withstand earthquake and blast loading. A demonstration of full-scale earthquake testing of this new seismic protection system will take place this Friday, November 19 at 1 p.m.

Development work undertaken over the past four years as part of Michael Gray’s doctoral research, under the supervision of Professors Jeffrey Packer and Constantin Christopoulos, is now in its final stage of validation. The testing on a full-scale one-storey frame is being carried out in the newly redeveloped Structural Testing Facilities at the University of Toronto Civil Engineering labs.

A brief overview of the $8-million upgrade of the Structural Testing Facilities, followed by a summary of the steel-casting research performed over the past few years with an emphasis on the development of the YBS system, will be presented prior to the full-scale real-time dynamic test.


WHAT: A demonstration of the research and development work at U of T Engineering in using steel castings to solve challenging structural problems, specifically enhancing the earthquake resistance and resilience of steel-braced frames.

WHERE: Sandford Fleming Building, 10 King’s College Road, Room 1009, at the University of Toronto

WHEN: Friday, November 19 from 1 to 2 p.m.

RSVP by November 18, 2010.
