Seismic Behaviour of Three Bay Four Storey In-Filled RC Frames

The scope of this study is to quantify the seismic behaviours in terms of load-deflection, ductility, stiffness degradation, and energy dissipation capacity of ¿ size three bay four storey RC in-filled frames with monolithic RC strips in the central bay. Further to retrofit, the partially damaged frame is strengthened with Ferro-cement followed by cement mortar grouting and the behaviour of both Control Frame (CF) and Retrofitted Frame (RF) is studied. The behaviour of in-filled RC frame mainly depends on the monolithic action of the whole system during ground motion. Here, the monolithic RC strip and infill acted as shear-wall in resisting the lateral load. The experimental results of the CF and RF are compared with the analytical results obtained by ANSYS software. von Paramasivam, Sathiaseelan
