Abstract
Bridges are one of the important components of vital transport infrastructure. In the last decade, single pier-column is spotted for bridge construction. Structural damages are significantly affected by the faulting mechanism, the directivity effect, soil classification and the superstructure properties, e.g. a high pile, the superstructure designation. The aim of this procedure is to study the near field and the far field effect on the nonlinear column analysis. When the studied earthquake is near field, the soil and the structure are reached to the plasticity and yielding and both of them, which are paid attention, are altered on the nonlinear response. According to what mentioned above, the nonlinear time history analysis of the pile-column response on the soft clay and the stiff clay is studied in the near field records with and without directivity effect by the OPENSEES software. The plasticity of column is modeled by Fiber Beam-Column Elements to simulate the earthquake responses in the OPENSEES software. The height of the column-pile is 40 m, which the embedment length of the pile is 30 m. The bedrock is confronted at -50 and is presupposed to be rigid. The results of hysteresis curves show that, the directivity effect increases responses of the Soil-Structure-Interaction of the Near Field.
