Abstract

Abstract This study is experimental and investigates the stability of reinforced concrete seismic walls, when at first subjected to different degrees of tensile deformation, and then strained under compressive load. The degree of tensile deformation refers to the elongation degree of the longitudinal reinforcement of the confined boundaries of load-bearing walls. The experimental investigation consists of ten prism test specimens of scale 1:3 simulating the extreme edges of structural walls. Specimens are reinforced using low longitudinal reinforcement ratio (1.79%), and high reinforcement ratio (3.19%). Specimens were subjected to different degrees of pre-tension, taking values equal to 0‰, 10‰, 20‰, 30‰, 50‰.
