- PublicaciónAcceso abiertoIdentificación de parámetros de comportamiento mecánicos de miembros tubulares de acero sometidos a carga cíclica(Universidad de Ibagué., 2020) Ramos González, Nicolás Daniel; Guerrero Chávez, Néstor LuisOn this work, we are going to identify parameters that are related to mechanical behaviors of square sections which are subjected to combined efforts of flexion compression which are produced by cyclic loads. From these experimental results which were made on tubular square section elements that were tested in Universidad Centro Occidental Lisandro Alvarado (Venezuela). Behavior Curves will be obtained for different values of axial load (0%, 15%, 25%, 40%) from the maximum axial load of the element with length 1200 mm and cross section (120 mm x 120 mm x 4 mm). The parameters to be determined would be yielding rotation, yielding momentum, ultimate rotation, ultimate momentum and critical rotation, which is the inelastic rotation at which the buckling occurs. These parameters will be used to define the plastic level values to be used in different behavior models used in different commercial structural software.
