Abstract

IN THE PRESENT PAPER, EFFECTS OF INCOHERENCY AND WAVE-PASSAGE ON NONLINEAR RESPONSES OF CONCRETE ARCH DAMS WERE INVESTIGATED. A DOUBLE CURVATURE ARCH DAM WAS SELECTED AS NUMERICAL EXAMPLE. RESERVOIR WAS MODELED AS A COMPRESSIBLE MATERIAL AND FOUNDATION WAS MODELED AS A MASS-LESS MEDIUM. GROUND MOTION TIME-HISTORIES WERE ARTIFICIALLY GENERATED USING MONTE CARLO SIMULATION APPROACH. FOUR DIFFERENT FE MODELS WERE CONSIDERED INCLUDING; UNIFORM EXCITATION; INCOHERENCE EFFECT; WAVE PASSAGE EFFECT AND; FINALLY BOTH INCOHERENCE AND WAVE PASSAGE EFFECTS. IT WAS REVEALED THAT MODELING MULTIPLE-SUPPORTS EXCITATION COULD HAVE SIGNIFICANT EFFECTS ON THE STRUCTURAL RESPONSE OF THE DAM BY INDUCING PSEUDO-STATIC EFFECT. ALSO, IT WAS CONCLUDED THAT COHERENCY EFFECT OVERSHADOW WAVE PASSAGE EFFECT AND RESULTS OBTAINED FROM NON-UNIFORM EXCITING OF FEM INCLUDING WAVE PASSAGE EFFECT IS CLOSE TO THE RESULTS OF THE FE MODEL EXITED UNIFORMLY.
