Reference number : GC-2017-Q2-00425, amendment number : , agreement type : G, recipient legal name : Alam, Shahria (The University of British Columbia), recipient country : CA, recipient province : nan, recipient city : British Columbia|Colombie-Britannique, recipient postal code : nan, program name english : Engage Grants for Universities, program name french : Subventions d'engagement partenarial pour les universités, program purpose english : More than 40% of Canadian civil infrastructure has passed its service life, and the municipal infrastructure_x000D_
deficit has grown to $141B (CIRC 2016). If immediate measures are not taken to revamp the infrastructure, the_x000D_
cost of replacement may increase manifold. Such deficient infrastructure also poses a serious threat to the_x000D_
public during disasters like earthquakes. A recent study conducted by the Insurance Bureau of Canada_x000D_
estimated the overall loss after a 9.0-magnitude earthquake in British Columbia at almost $75B (IBC 2013),_x000D_
which clearly reflects the vulnerability of Canadian civil infrastructure. In order to avoid such scenarios in_x000D_
Canada, and in other earthquake prone regions across the world, it is imperative to take immediate measures._x000D_
The proposed research will introduce prefabricated post-tensioned steel bridge pier that will not only enable_x000D_
structures to be built faster but also help structures self-center after major earthquakes. Such structures will be_x000D_
immediately serviceable requiring no major repair works._x000D_
Performance-based design is becoming a standard practice for seismic design and evaluation of structures in_x000D_
order to achieve a reliable and satisfactory level of performance. However, there has been no study on the_x000D_
seismic performance of such self-centering steel bridge piers. This research will help develop proper_x000D_
understanding and knowledge about the behavior of such bridges, which will eventually help us develop the_x000D_
performance-based design guideline for such bridges. This study will assist engineers in examining the_x000D_
interaction among different components of the bridge under lateral loads, and evaluate its limit states, and_x000D_
determine adequate section sizes and connection details and provide design implications. Finite element_x000D_
method (FEM) will be implemented in this study where the models of self-centering bridge piers will be_x000D_
generated in ANSYS FEM environment. Extensive FE analysis will be performed to determine the effect of_x000D_
different parameters including the steel strength, dimensions, amount of post-tensioning force and energy_x000D_
dissipator characteristics on its behavior, and the preliminary design requirements., program purpose french : More than 40% of Canadian civil infrastructure has passed its service life, and the municipal infrastructure_x000D_
