Abstract

Steel beam-to-column joints are often subjected to a combination of bending and axial forces. The level of axial forces in the joint may be significant, typical of pitched-roof portal frames, sway frames or frames with incomplete floors. An approach, based on finite element modelling, is presented in order to numerically investigate the seismic performance of bolted steel end-plate moment connection by including the effect of axial forces in the connection. Current specifications for steel joints do not take into account the presence of axial forces (tension and/or compression) in the joints. A single empirical limitation of 10% of the beam’s plastic axial capacity is the only enforced provision in Annex J of Eurocode 3.The methods for applying loads to the connection were considered to be only monotonic loadings. For the nonlinear finite element analysis the modelling process was carried out using ABAQUS computer program. The results of the finite element analysis of the connection showed that by applying the tensile axial load of the beam into the connection the ultimate bending capacity of the connection will decrease. Finally, it reveals that the presence of an axial force on the beam significantly modifies the joint response.
