Seismic design of bridge piers
WebIn this study, the seismic response and damage behavior of an isolated bridge under near-fault ground motion are studied and compared with the non-isolated bridge. To consider the local damage of the bridge pier and its evolution process, the nonlinear behavior of the bridge pier in the analysis is simulated by the fiber beam-column element model … WebSeismic Design of Concrete-Filled Circular Steel Bridge Piers Michel Bruneau, M.ASCE,1 and Julia Marson2 Abstract: The adequacy of the existing design provisions for concrete …
