Abstract:

Hybrid structure consists of steel frame and reinforced concrete core tube. The steel beams are welded or anchored to the embedded steel parts in concrete wall, and then concrete slab is cast at the floor level. These stiff joints are easily damaged under earthquakes. This paper describes a comparative study on the seismic behaviour of hybrid structure with stiff connection and with viscous damper connection by using lumped storey model for structural analysis. Numerical results show that proper viscous damper connection can significantly improve the seismic performance of the structure.
