EQE 586- NON-LINEAR SEISMIC ANALYSİS OF REINFORCED CONCRETE BRIDGE STRUCTURES

INSTRUCTOR : Göktürk ÖNEM, Ph.D.

COURSE OBJECTIVES :

Non-linear modeling and analysis approaches for bridge type of structures.
Design principles
Deformation based design concept
Seismic isolation solutions for bridges

COURSE SYLLABUS : This course mainly aims at presenting on non-linear modelling and non-linear analysis methods of reinforced concrete bridge type structures for the purpose of understanding inelastic behavior under earthquake effect. Non-linear analysis methods will be explained with the emphasis on non-linear static analysis methods (Pushover). Deformation-based design approach and utilizing non-linear analysis within the framework of performance-based design principles will be summarized. Conceptual design principles of bridge type structures and code-based design approach (in AASHTO and Eurocode) will be presented. Seismic performance assessment of existing bridges will be summarized with computer-based numerical examples interactively.

PREREQUISITES : EQE 530, EQE 550

DURATION & HOURS PER WEEK : 3 hours per week

GRADING BASIS : Homeworks and term project and its presentation at the end of course duration
