Estudio del reforzamiento de mampostería de bloque de hormigón mediante ensayos destructivos aplicados a pórticos de acero con juntas apernadas.

Abstract

The purpose of this research work is to study the reinforcement of concrete block infill masonry in steel frames with bolted connections through destructive testing. This study focuses on the mechanical characterization of the materials and the applied reinforcement system, as well as on the construction and testing of steel frames with infill masonry. To achieve it, we proceeded to select materials and geometries that are used in construction and that allow the development of a methodology for both construction and testing under laboratory conditions. In this way, tests were carried out on masonry specimens, masonry units and mortar with specific procedures for each one, in order to determine the necessary mechanical parameters in this study. Two prototypes of steel frames with infill masonry were tested for four scenarios or case studies by applying cyclical lateral load induced by a hydraulic actuator in the laboratory, with an established procedure, in this way, the behavior of these prototypes was characterized experimentally. Finally, the experimental results were compared with those obtained from an analytical model obtained from the results of the mechanical characterization tests of the materials.
