Abstract:
Pseudo-static cyclic loading tests of a single-layer and single span prefabricated eccentrically braced steel frames were carried out and the test results were simulated by ABAQUS software. On the basis of reasonable results, five finite element models were established. The influence of web openings on seismic behavior of prefabricated eccentrically braced steel frames was analyzed from bearing capacity, stiffness degradation and energy dissipation capacity. The results showed that the opening ratio of web of link had influence on its bearing capacity in the monotonic load, the yield bearing capacity and ultimate bearing capacity of model decreases with the web opening ratio. Under cyclic loading, the initial stiffness of the model decreased with the increased of web opening ratio. The energy consumption capacity of model was not affected obviously by the opening ratio, except for BASE model: the energy consumption coefficients of other models are around 1.55. Appropriate increase of opening ratio could improve the ductility coefficient of the model, however, too large opening ratio would lead to premature failure of the component, which would make the reduction of ductility coefficient.
