Abstract: Composite core walls with concrete filled steel tubes (CFT) composite column borders are the main structure of Dalian Conference Center.Ensuring the anchorage reliability between the CFT column and the concrete foundation is one of the key technologies in seismic design.According to the engineering structure,three 1/5 scale specimens of CFT column base bedded in concrete foundation were made,and the experiments under cyclic loading were carried out.Through the experiments,the effect of foundation reinforcement on anchorage performance of the specimen is studied.Results show that increasing horizontal distribution bar at the top of the anchor plate may improve the ultimate loads and ductility.Increasing anti-punching shear bar may effectively improve the ultimate loads.The anchorage performance of prototype of test specimen is reliable,and the construction methods in engineering can meet design requirements.
