Real-time hybrid method is an economical and efficient test method to evaluate the dynamic behavior of infrastructures. The purpose of this paper is to prove the reliability of a real-time hybrid system with concrete structures expecting severe nonlinear response rather than steel structures. For the test specimen, a column in 3 bay-3 story building is selected as the physical substructure and four types of beam column elements are used in the numerical model. Northridge earthquake is applied as ground acceleration. As a result, the maximum error of numerical analysis is 13% comparing with the result of shaking table test. However, the result of real-time hybrid test shows good agreement with the shaking table test. Therefore, real-time hybrid method can be used effectively to predict the dynamic behavior of concrete structures.
