STRESS MECHANISM OF PREFABRICATED BEAM-COLUMN CONNECTIONOF STEEL STRUCTURE WITH END PLATE
Translated Abstract
A prefabricated beam-column connection of steel structure with end plate component was proposed, which was composed of a circle tubular steel column with cantilever beam, an ordinary beam and the comection between the two devices.The connection stiffness could be adjusted by the modification of parameters, including the thickness of the cover plate and the distance between the bolts beside the splice gap.With this method, energy dissipation could be realized by the deformation of the cover plate to ensure that plastic failure would not occur on the main members, which was necessary for the rehabilitation after earthquake.The numerical simulation of 6 beam-column connections was carried out and several parameters were obtained, such as the bearing capacity, failure mode,member stress and the change in bolt tension,etc.More attentions were paid to the influence on the mechanical properties caused by the thickness of the cantilever beam flange, the width of the gap between the end plate members, the distance between the bolts beside the splice gap, the thickness of the cover plate and the material properties of the cover plate.Analysis showed that the bearing capacity could be guaranteed by the reasonable design of relative parameters of bolts and cover plate, which could also avoid the damage of the main members such as beams and columns.In this way, the rehabilitation after earthquake could be achieved.
