3. Seismic Performance of RCS Composite Joints Under Floor Effect
- The concrete floor is bound to the column Tie;
- The reinforcing bars in the floor slab are combined into a reinforcing bar layer and embedded in the concrete area;
- The rivet contacts the tie binding the bottom of the floor slab with the upper flange of the steel beam. The finite element model of node FJD-0 is shown in Figure 11.
- The floor effect changes the node damage form and enhances the connection strength, with the maximum stress concentrated in the connecting bolt and the plastic hinge occurring at the end of the beam, which conforms to the design code of “strong column weak beam”. The strength of the connecting bolt should be strengthened.
- Compared with RCSJ3, FJD-0 significantly improves the bearing capacity and stiffness, and improves the seismic performance.
- The positive and negative direction yield loads of node FJD-0 increased by 78.9% and 70.0%, respectively, while the ultimate bearing capacity improved by 13.2% and 9.98%. The energy dissipation capability increased by 23%, and the stiffness of all loading loops was enhanced, leading to a significant improvement in overall stiffness and a slower rate of strength degradation, as well as enhanced strength retention. The participation of the floor slab slightly reduced ductility, but to a minor extent, still meeting seismic design requirements. In seismic design, attention should be paid to the interaction effects of the floor slab to optimize the node structure and enhance the overall seismic performance [31].
