The vast majority of bridges are relatively simple structures. This is most true for girder bridges whose span range has increased significantly to cover nowadays a vast proportion of bridges being built. De-spite their simplicity however bridges still pose challenging problems due to their dimensions and plan-extended character. Construction phases often dominate the superstructure design. From the seismic analysis point of view their simplicity is not associated with an equally simple and regular dynamic response. This pa-per presents an overview of recent research on the seismic design and assessment/retrofit of bridges focusing on some of the aspects which are still not adequately covered in the codes such as: the level of protection to be used when designing a new bridge; the level of protection to be provided when upgrading an existing bridge and in particular whether this should be differentiated with respect to that adopted for design; the appropriate methods of modeling and analysis with emphasis on the scope of nonlinear static methods and to the problems related to the selection of the input for response history analysis; soil-foundation-structure interaction (piers abutments integral bridges) and non-uniform support input representing two controversial issues that may be mature for an inclu-sion in routine bridge analysis.
SHORT BIO
Dr. Franchin is an Assistant Professor in Structural Design at the Department of Structural Engineering and Geotechnics of Sapienza University of Rome. He graduated with honors in Civil Engineering from Sapienza University of Rome in 1997 received a MSc in Structural Engineering from University of California Berkeley in 1999 and a doctoral degree from Sapienza in 2001.
His research is in the fields of Earthquake Engineering and Structural Reliability where he has more than 50 publications including a textbook on topics such as the seismic design and assessment/retrofit of bridges critical facilities such as hospitals and infrastructural systems. He is a member of Commission 7 "Seismic design" and of Task Groups 7.5 "High-performance materials and structural systems" and 7.7 "Performance-based Seismic Design" of the International Federation of Structural Concrete (fib). He is also a member of Sub-Committee 3 "Structural Reliability and Optimization" of the International Association of Structural Safety and Reliability (IASSAR).
