摘      要：The main purpose of this paper is to investigate the effect of core eccentricity on the structural behavior of concrete tall *** buildings of 55 floors with plan dimensions 48.0×48.0 m2 were *** cases of main core locations are studied:centric(A),eccentric by one sixth(B)and one third(C)of building *** three-dimensional finite element method has been used in conducting structural analysis through ETABS *** and lateral(wind and seismic)loadings are applied to all building *** has been concluded that the core location is the prime parameter governing the structural behavior of tall *** the first two cases(A,B)have acceptable and similar structural behaviors conforming to code limits,in the third case(C),the building behavior came beyond code *** author introduced remedial action by adding two secondary cores in the opposite direction of the main core(C-R)to restore the building behavior to the code *** results of this action were satisfactory.
