SUMMARY:Structures Seminars – Muntasir Billah (Calgary): Shape Memory All
 oy for Multi-hazard Resilient Design of Highway Bridges
DESCRIPTION:Abstract:\nReinforced concrete (RC) bridges are currently desig
 ned to withstand severe natural and human-made hazard without collapse\, b
 ut damage of concrete and yielding of reinforcing steel bars are allowed.
   Excessive damage increases downtime\, and sometimes the structure is be
 yond the repair stage and must be replaced.  In recent years\, shape memo
 ry alloy (SMA) rebars have been widely employed to improve the performance
  of concrete structures and reduce their permanent deformations\, especial
 ly when subjected to seismic and extreme loads. Although the effectiveness
  of SMA as reinforcement in seismic resistant design is well documented\, 
 performance of SMA-RC bridges under various multi-hazard scenario is not w
 ell understood. Currently available design codes and guidelines are adequa
 te in addressing individual issues related to resilient bridge design\, bu
 t fail in addressing the complexities in a multi-hazard environment\, wher
 e these dependencies exist at multiple levels. This seminar will introduce
  the recent efforts on extending the bridge design concept using a perform
 ance-based approach from single hazard to multihazard to ensure enhanced r
 esilience and protection\, thus minimizing the adverse social and economic
  impacts of multiple hazards. To investigate the resiliency of RC bridges 
 against multi-hazard scenarios\, this presentation will discuss the perfor
 mance of SMA-RC bridges under three extreme loading scenarios such as eart
 hquake\, vehicle collisions\, and extrme wave loads. This study will prese
 nt the details of the vehicle collision and wave load simulation in finite
  element environment. The results will be compared with conventional Steel
 -RC bridges under similar loaidng conditions. The outocmes of this study w
 ill aid in understanding the advantages of SMA as longitudinal reinforceme
 nt for improving the multihazard resiliency of highway bridges.\nBio:\nDr.
  Muntasir Billah is an Assistant Professor in the Department of Civil Engi
 neering at the University of Calgary\, Canada. He received his PhD in stru
 ctural engineering from the University of British Columbia\, Canada. Dr. B
 illah was awarded the 2016 UBC Governor General’s Gold Medal—one of Ca
 nada’s most prestigious academic awards. Dr. Billah’s research has gai
 ned both national and international recognition with 65 peer-reviewed jour
 nal papers\, more than 75 conference papers\, and 9 invited presentations.
  Dr. Billah aims to amalgamate conventional engineering and application of
  advanced materials and tools to devise solutions that make the infrastruc
 tures more sustainable and resilient. Currently\, Dr. Billah is serving as
  the chair of the concrete structures sub-committee of the Structures Divi
 sion\, Canadian Society for Civil Engineering (CSCE)\, and voting member o
 f ACI Committee 341\, Earthquake-Resistant Concrete Bridges. His research 
 interests include performance-based seismic design and retrofit of bridges
 \, multi hazard resilience of infrastructure\, application of high-perform
 ance materials and artificial intelligence in structural engineering.\nOpe
