Comportamiento de componentes T-equivalente asimétricasenfoque analítico, numérico y experimental

Abstract

This research addresses the study of asymmetric T-stub components subjected to tensile loads, through analytical, numerical and experimental approaches, referred this asymmetry to the position of bolts to the web. The main objective is to calculate the properties of strength and stiffness, and compare them with symmetric components.The behaviour of the component was characterized through an equivalent matrix model, where the parts are considered as frame elements. The internal forces calculated were used to evaluate the ultimate resistance and the stiffness, taking into account the effect of shear. Values obtained were compared with experimental results from 2 tests developed in both symmetric and asymmetric configurations. The model fits to the experiments with allowable precision. Finite elements simulations from models tested and from end plate connections were carried out also, in order to study additional parameters estimate the suitability of the component proposed to the global behavior of the connection.
