The majority of existing bridges not designed to withstand earthquake need to be evaluated to determine the level of their performance with respect to the seismic ground motion to which they may be subjected. The purpose of seismic retrofit of bridges is to identify the supporting elements that are vulnerable to seismic effects, to evaluate their resistance and to enhance their capacity to absorb the energy imposed during a seismic event. This course offers, through case studies of examples based on the bibliography, the options of seismic evaluation and retrofit of bridges..
Identify the resisting elements and foundation units that are vulnerable to earthquakes.
Identify the type of structures that are vulnerable to earthquakes.
Know the soil type vulnerable to seismic movements.
Identify the important parameters necessary for increasing the strength of structural elements.
Apply the techniques of retrofit of resisting elements and foundation units of bridges
Introduction to seismic waves
Fault geometry, seismic waves, earthquake properties and seismic hazard
