Authors:    Muhammad Tayyab Naqash, Giuseppe Brando, Gianfranco De Matteis
Abstract:  Finite Element Method (FEM) is an affective numerical technique oftenly used for solving models in differential form. For detailed study of any experimental test it is useful to develop a finite element model that aids in simulating the result of the experimental test precisely. This research paper is aimed at calibration and validation of an accurate numerical model. Initially, the models are suitably calibrated on the basis of experimental tests conducted by De Matteis et al [1, 2] for aluminium T-stub connections. In addition, these numerical models are also calibrated and consequently validated for the steel material using the experimental tests of Bursi and Jaspart [3, 4]. Furthermore, this paper also highlights sensitivity analysis for mesh size of different component of metal connections and different contact interations with several friction coefficients. With the help of force-displacement curves intereting results showing the accuracy of the model are provided. It is believed that the paper will help the researchers who are involved in the calibration of numerical models for metallic structures.
