ABSTRACT:In this paper, a hysteretic model with pinching is presented that is able to reproduce realistically the cyclic response of generic steel joints. Secondly, the computer implementation and adaptation of the model in a spring element within the computer code SeismoStruct is described. The model is subsequently calibrated using a series of experimental test results for steel joints subjected to cyclic loading. Finally, typical parameters for the various joint configurations are proposed.Keywords: structural engineering, steel structures, buildings, component method, beam-to-column joints, dynamic behaviour, seismic behaviour, joint model INTRODUCTIONThe behaviour of steel or composite joints under cyclic loading is characterized by hysteretic loops with progressive degradation of strength and stiffness that eventually lead to failure of the joint. A typical natural event that, for simplicity, is usually approximated by cyclic loading is an earthquake. Usually, seismic events provoke relatively high amplitudes of rotation in the joint area, so that steel repeatedly reaches the plastic range and the joint fails after a relatively small number of cycles. This typical behaviour is usually called oligocyclic fatigue, in close analogy with the behaviour of steel under repeated cyclic loading stressed into the plastic range (Fig. 1a).

“…The angles are welded to the beam-web and bolted to the column flange using eight ¾ in (19 mm) diameter high strength bolts. Further investigation conducted by Abolmaali et al [1] indicates that this model is failed due to excessive yielding of the angles. Same failure mode was observed during the finite element analysis as shown in Figure 21.…”

The presented manuscript is intended to introduce accurate computational benchmarks to predict the hysteresis behavior of beam-column steel connections by means of a 3D non-linear finite element analysis. In this study, element type, inelastic material behavior, bolts pre-tensioning, and contact properties between different components of connections are discussed. Incremental nonlinear analysis takes into account all three types of nonlinearities including material, geometry, and contact properties in predicting moment-rotation hysteresis loops. A series of full-scale structural tests are performed to validate the results obtained from the finite element analyses. This study shows that cost efficient numerical analysis simulation is capable of replacing full-scale tests for steel connections.

This paper presents the analytical results of six steel bolted T‐connection models and four steel bolted beam‐to‐column connection models with top and seat angles. This study was undertaken to analyse the influence of bolted T‐connections instead of welded connections and the influence of angles with and without stiffeners on the behaviour of the beam‐to‐column connections under hysteretic loading. The aim was to compare the energy dissipation of different connections with each other. The energy dissipation characteristics are obtained from the main characteristics of moment‐rotation hysteresis curves. This study shows that the energy dissipation decreased by about 2–29 % and 2–13 % for bolted T‐connection and top‐and‐seat‐angle connection models respectively after switching from one cycle to another in five hysteretic loadings.
