Abstract
A new type of connection node filled with steel tubular column is proposed for the frame structure of concrete. In this paper, the mechanical properties and failure mechanism are studied. As shown by the finite element analysis results, the hysteresis curve attains the full standard, indicating that the joints possess good deformation performance, as well as good bearing capacity, ductility and energy dissipation capacity. Based on the results of the finite element analysis, the experimental study of this type of node is carried out. Meanwhile, a series of experiments are conducted to enhance the length of the steel plate, the effectiveness of the steel plate and the thickness of the protective layer of the steel plate.
