DESCRIPTION:Prof. Dr Robert Tremblay\, Département des Génies Civil\, Ec
 ole Polytechnique de Montréal\, Canada\nabstract : This presentation will
  introduce structural steel seismic force resisting systems that have been
  proposed to enhance the response of structures to earthquakes. The focus 
 will be on braced frames used for building structures. The eccentrically b
 raced frame system with replaceable ductile links will be introduced as an
  example where a minor modification can reduce fabrication costs\, improve
  the seismic response and help post-earthquake recovery. Concentrically br
 aced steel frames modified to exhibit self-centering response and eliminat
 e structural damage by using either special brace members\, rocking respon
 se or a combination thereof are then discussed. Controlled rocking respons
 e generally result in reduced seismic induced force demands on the structu
 re and its foundations compared conventional designs. Such reductions can 
 be significant and can be achieved at low cost for short-period\, low-rise
  buildings responding essentially in their fundamental mode\, which makes 
 the concept attractive for the seismic retrofit of seismically deficient b
 uilding structures. Single-storey steel buildings with large foot prints t
 hat are used for commercial and light industrial applications or sport fac
 ilities represent a large portion of the building stock in Canada. Seismic
  resistance for these structures is typically obtained using an horizontal
  roof diaphragm acting with vertical braced frames. Ductile brace fuses an
 d rocking braced frames will be presented as options that can be implement
 ed to enhance the response and reduce construction costs. Lastly\, the pre
 sentation will discuss structural systems that are being investigated to a
 chieve stable inelastic response for tall braced frames. These will includ
 e frames equipped with segmental elastic trusses and frames that are desig
 ned to exhibit post-yielding lateral stiffness.\n\nBio : Robert Tremblay i
 s Professor of Structural Engineering at Polytechnique Montreal\, Canada. 
 He received his Bachelor (1978) and Master (1988) degrees from Université
  Laval and completed his Ph.D. in 1994 at the University of British Columb
 ia in Vancouver. Before undertaking his doctoral studies\, Prof. Tremblay 
 worked for 10 years in the industry. He held a 14-year Canadian Research C
 hair in earthquake engineering between 2003 and 2017. His current research
  work is mainly directed towards the seismic design and response of steel 
 structures. He is a member of the Standing Committee on Earthquake Design 
 for the National Building Code of Canada\, the CSA-S16 Technical Committee
  on Steel Structures for Buildings\, the CSA S6 Technical Sub-Committee on
  Seismic Design of Bridge Structures\, the AISC Task Committee 9 on seismi
 c design of steel structures and the AISC Adhoc Task Group on Non-Building
  Structures and Industrial Buildings.
