Abstract

Due to many advantages, prefabricated buildings are the trend of future development. In order to study the mechanical properties of the steel structure beam-beam connection node, referring to related materials, this paper designs a bolted connection node between main and secondary steel beams. By changing the key parameters such as the thickness of the supporting plate and the diameter of the bolt, the finite element software ABAQUS is used to simulate the primary and secondary beam nodes. Based on the finite element results, the force mechanism, failure mode, flexural bearing capacity and rotational stiffness of the nodes are analyzed, and some parameter design suggestions are proposed: the thickness of the supporting plate should not be less than 8mm, and the bolt diameter should not be less than 20mm.
