Designing and building safe structures against seismic hazards has always been one of the important goals in civil engineering. One of the biggest challenges in this direction is predicting the response of structures against dynamic loads. Practical tests and experimental tests have been powerful tools to understand this properly. Experimental methods that have been used for this purpose in the past are: quasi-static method and shake table method. Among the drawbacks of these methods, we can mention the inapplicability of the quasi-static method for structures with components dependent on the speed rate and high cost of building large-scale models and the scarcity of laboratories equipped with full-scale shake tables in the world. The hybrid simulation method is an advanced method that combines the physical experimental model with the computer numerical model. This method provides accurate solutions for complex structures. The versatility of this method in simulating the seismic responses of full-scale models , and also the lack of need to build a real physical model of the structure, have made this method efficient in analyzing all kinds of structural systems. In this study, a new type of self-centering column base has been investigated using this method. And by dividing the studied structures into numerical and experimental sub-structures and using UT-SIM middleware to connect these sub-structures, the hybrid simulation process was carried out. Finally, this study showed that the hybrid simulation method is an efficient method for eva‎luating the seismic performance of different structural systems. And it can be a suitable and economical alternative to help researchers in the progress of earthquake engineering science.
