Estudio del comportamiento de muros de corte de placas de acero rigidizadas ante cargas cíclicas.

Abstract

The analytical and experimental study of steel plate shear walls (SPSW) with plate stiffeners is presented, a variant that has been dormant within the development of SPSW walls due to the concepts that describe the steel plate behavior before the application of shear loads parallel to the wall main plane, where the same theory allows to evaluate possible results when using stiffeners that increase the capacity of the plate before these load demands; to demonstrate these concepts, three samples of the wall with a stiffened plate, a sample of this with an unstiffened plate and a sample of the frame were created, reaching results where the walls with stiffeners presented a higher shear capacity than the unstiffened wall in a 27%, and the frame developed a good capacity of displacements, thus focusing the contribution of rigidity to the steel plate.
