摘要

Bridge structures built in regions with high probability of earthquake strokes and strong ground motion acceleration peaks require a highly sophisticated design in order to fulfill operational performance and dynamic safety of the structure. In order to approach the optimal design of these structures, numerical simulations of dynamic structural response due to ultimate limit loads are required. Nonlinear material models, such as concrete cracking and crushing as well as yielding of steel reinforcement have to be taken into account to obtain structural response close to reality under ultimate limit load conditions. This paper discusses application of numerical simulations performed for reinforced concrete columns under earthquake loads using linear and physically nonlinear fiber models. Nonlinear material models can be used to introduce softening zones into the structure by purpose and therewith reduce maximum internal forces.
