DESCRIPTION:Prof. Bozidar Stojadinovic\nCommunities are complex systems of
  people\, structures and infrastructure\, both physical and social. Respon
 se of communities to disasters is much more than the sum of the responses 
 of its constitutive parts. Yet\, today\, design methods are focused on ind
 ividual structures\, as if they each were standing alone. For example\, we
  have tools to predict the seismic response of individual highway bridges 
 but we lack methods to predict the response of the entire regional highway
  system to a disaster. Resilience of communities is\, therefore\, difficul
 t to engineer using the present framework.\nIn this talk I will present a 
 probabilistic performance-based framework for engineering resilient commun
 ities that addresses systems of structures and infrastructure rather than 
 collections of individual entities. First\, I will attempt to define the s
 eismic resilience of communities\, and describe the \nproperties of a perf
 ormance-based community-level seismic design framework.\nSecond\, I will i
 llustrate the fundamental knowledge\, enabling technologies\, and engineer
 ed systems needed to constitute the new framework using \nthree examples f
 rom my ongoing research: rocking of post-tensioned bridge columns\; modeli
 ng bridge ability to carry traffic load after an earthquake\; and evaluati
 on of how new technologies and materials\, such as base isolation and fibe
 r-reinforced concrete\, affect system design choices.\nThird\, I will conc
 lude by outlining the framework for performance-based engineering of resil
 ient communities\, focusing on the changes in hazard exposure and performa
 nce objective selection. I will also discuss the new research needed to im
 plement such design framework in civil engineering practice. Society of to
 morrow must have an order of magnitude more confidence in the resilience o
 f the physical and social infrastructure then it does today.\nPerformance-
 based engineering of resilient communities is an important contribution Ci
 vil Engineers can make towards this worthy goal.\nBio: Dr Bozidar Stojadin
 ovic recently joined the ETH Zurich as full professor of Earthquake Engine
 ering and Structural Dynamics. His research interest comprise\, for exampl
 e\, the development of probabilistic performance-based seismic design tool
 s and the simulation of earthquake motion and response of structures in an
  urban region. Bozidar received numerous awards among these the ASCE Walte
 r L. Huber Civil Engineering Research Prize in 2004.
