Abstract: This paper presents a new connection model, Mild Steel Node, for the concrete filled circular steel columnsteel beam system. The node is finite element analyzed by using ANASYS software. The results indicate that the concrete filled circular steel columnsteel beam with mild steel nodes is an ideal seismic energy dissipation connection. The length of the mild steel connections is also optimized based on the numerical analysis results.
