Influence of shear walls on the structural behavior of a multi-storey concrete building according to Brazilian Technical Code ABNT NBR 15421:2006

abstract: This paper presents a comparative study of the influence shear walls on behavior multi-storey concrete building when subjected to seismic actions. Two structures with different earthquake-resistant systems were evaluated. One is composed frames usual detailing in both directions (x and y), other one formed by dual system, detailing. The Equivalent Lateral Force procedure Modal Response Spectrum analysis presented Brazilian Technical Code ABNT NBR 15421:2006 considered. system greater stiffness arranged parallel direction y. In x direction, responses are equivalent buildings. horizontal forces obtained method at base buildings than method.
