Abstract

THIS STUDY FOCUSES ON PERFORMANCE OF CFT COLUMN TO FOUNDATION CONNECTIONS SUBJECTED TO COMBINED AXIAL AND LATERAL CYCLIC LOADING. EXPERIMENTAL INVESTIGATIONS WERE CARRIED OUT ON FIVE SPECIMENS WITH EXPOSED COLUMN BASE AND EMBEDDED COLUMN BASE CONNECTIONS. THE PARAMETERS CONSIDERED&AMP;NBSP; WERE NUMBER OF STIFFENERS AND EMBEDMENT DEPTH OF CFT COLUMN. THE FORCE - DISPLACEMENT RESPONSE OF ALL THE SPECIMENS WERE COMPARED. PROVIDING INCREASED NUMBER OF STIFFENERS, INCREASE THE STRENGTH OF CONNECTION. AN ADDITIONAL MESH PROVIDED ON THE EMBEDDED CONNECTION WAS FOUND TO BE GOOD IN IMPROVING THE DUCTILITY OF THE CONNECTION WHICH IS A FEASIBLE SOLUTION FOR COMPOSITE STRUCTURES IN EARTHQUAKE PRONE REGIONS.
