Abstract

The unpredictable nature of EARTHQUAKE has led to engineers to the statistical and probabilistic studies for investigating of the effects of EARTHQUAKE phenomenon problem. The movement recorded of the ground under influence of EARTHQUAKEs in near fault zones are different from FAR FIELDs. The pulse phenomenon in the history of acceleration, velocity and displacement is one of the characteristics that distinguishes near and FAR FIELD EARTHQUAKEs. In this research, after scaling the time histories of accelerations, structural analysis of REINFORCED CONCRETE BRIDGE with four 22 meters openings has been performed by dynamic analysis of liner history. Then, the results in the form of internal forces of the members and displacements in a particular joint under the time history of accelerated incidents are presented. The result of investigating the effects of bridge DISTANCE FROM FAULTs on internal forces of columns due to EARTHQUAKE showed that axial forces including compressive, tensile and torsional moment in columns have the highest value when NEAR FIELD EARTHQUAKE occur. Also, the result of evaluating the effects of bridge DISTANCE FROM FAULTs on internal forces of deck due to EARTHQUAKE showed axial force and bending moment at time of FAR FIELD EARTHQUAKE happen have highest value. Although, this amount is dependent on severity of EARTHQUAKE.
