Abstract

Abstract: Lateral buckling is a severe phenomenon that takes place in reinforced concrete structural walls under severe seismic action and can lead to total collapses. One critical mechanical parameter affecting the lateral buckling phenomenon is the degree of tensile strain that the wall boundary edges have been subjected to during the cyclic loading of seismic action. This phenomenon is studied here for the first time for such a large degree of elongation, modelling a severe seismic action leading to the appearance of out-of-plane buckling. The study herein involves a tensile strain equal to 60‰. Afterwards, compression loading is applied until failure. A prism specimen is used to model the boundary edges—a practice well established worldwide. Useful conclusions arise from the application of such a large degree of tensile strain.
