Estudio y análisis del comportamiento de varillas de acero corrugado A706 bajo la acción de cargas cíclicas.

Abstract

Reinforcing steel is widely used in concrete constructions, considering an ideal and homogeneous behavior, although this steel is clearly known its static behavior, this research analyzes its behavior submitted the action of cyclic loads, producing fatigue of low cycles. Identifying variables that affect the exhaustion of the different specimens of the different nationals steel producers, providing information that aims to improve the quality of steel. Destructive tensile - tensile tests were develovment out on specimens obtained from commercial bars with diameters 14, 16 and 18 millimeters in a universal programmable test machine, controlling the load application force until finish the mechanical capacity, obtaining reproducible results. Determining a tendency of fracture due to the geometry in two of the marks analyzed, decrease of ductility in all the marks analyzed by application of welding, the similar base material with which they are constructed. Establishing a possible experimental method to evaluate the behavior of reinforcing steel under the action of cyclic loads.
