“…Wald and Svarc (2001) tested three flush endplate beam-to-beam joints and two extended endplate beam-to-column joints; however there is no reference to tests made with only bending moment, which is important to study the influence of the axial force in the joint response. Lima et al (2004) and Simões da performed tests on eight flush endplate joints and seven extended endplate joints. The investigators concluded that the presence of the axial force in the joints modifies their structural response and, therefore, should be considered in the joint structural design.…”

“…It is worth highlighting that the incorporation of this approach into a nonlinear semi-rigid joint finite element formulation does not require steps (d) and (e), because the complete joint modelling already considers all the possible situations of loading through each component force-displacement characteristic curve. In order to explain how each step is evaluated, six extended endplate joints tested by Lima et al (2004) were tested.…”

Cyclic behaviour of steel beam‐to‐column joints and calculation tools

et al. 2021

The seismic design of dissipative beam‐to‐column steel joints is currently allowed in Eurocode EN1998 only when supported by tests due to the lack of reliable models for predicting their behaviour under cyclic conditions. On the other hand, the well‐known component method coded in EN 1993‐1‐8 (EC3‐1‐8) only applies to monotonic response of the joints. In this paper, an extension of this method, cyclic component method (CCM), is presented, which was developed and implemented for cyclic conditions in the scope of the research project EQUALJOINTS. The CCM was developed to predict the joints moment‐rotation behaviour for a wide range of joint configurations by properly combining cyclic force‐elongation behaviour of relevant components using the Modified Richard‐Abbott model. The step‐by‐step development and implementation of the CCM addresses (i) widespan variety of joint configurations and (ii) is fully compatible with the prescriptions in EC3‐1‐8. An example of application of the method is shown for an end‐plate beam‐to‐column steel beam‐to‐column joint, highlighting the level of accuracy achieved so far in the simulations of the cyclic behaviour of joints. The work performed so far shows promising results and good perspectives for new developments, which are identified making use of evidence from the results of the application example.

This research deals with the axial‐bending interaction in bolted steel beam to column connections along the strong axis of the column. In order to define the interaction curves, firstly, a series of tests of doubly symmetric bolted connections were carried out in which two column sizes were considered, while the beam, end plate and bolts remained the same. These joints were tested under pure compression, as well as simultaneous bending and compression, and with different load levels. Afterwards, reduced finite element models including initial imperfections were made. These models are validated by means of the results obtained in the experimental program. The aim of the reduced model is to enlarge the range of studied loading combinations in terms of different percentages of axial load and bending moment. Finally, with the results obtained, a preliminary normalized interaction diagram for this type of joints was deduced.
