Design and Evaluation of Reinforced Concrete Bridges for Seismic Resistance

摘要

Seismic design approaches for reinforced concrete bridges are reviewed, anduncertainties in seismic design and evaluation are discussed. The modeling of bridge components and systems is discussed, and analytical studies of the response of series of simple bridges are made. The relative utility of several design approaches and stiffness assumptions for controlling seismic demands is assessed. Modeling of column and wall pier flexural and shear strengths is examined in detail, and available models for the inelastic shear strength of columns are compared with test data. Displacement-based approaches are shown to be effective for controlling displacement ductility demands, particularly for short period structures for which conventional, strength-based design approaches are often less effective.
