Research on Seismic Performance of Prefabricated Cantilever Beam Steel Structure Nodes

In this paper, the seismic performance of a cantilever beam steel structure with beam-column nodes is investigated.Using ABAQUS software, three types of nodes are modeled and analyzed with and without soft steel dampers as well as ordinary steel structures, and the seismic performance of the three types of nodes is quantitatively analyzed in terms of their hysteresis curves, skeleton curves, stiffness degradation, and other seismic performance. The results show that the nodes with dampers have the strongest mechanical properties in each, the nodes of ordinary steel structure are second, and the nodes without dampers are the worst. It can significantly consume the seismic energy of the building structure and reduce the seismic response in a controlled situation. Therefore, this node is conducive to the popularization and use of assembly structures in high-intensity areas under controlled circumstances, which can effectively improve the seismic performance of assembly structures and provide a reference for assembly building construction in practical application.
