The concrete building represented an existing structure that doesn’t satisfies the seismic requirements in the current design code, while the steel building was coupled with the concrete building by friction damper aimed to upgrade the seismic capacity of the concrete building. The online test results have indicated that the cyclical behavior of the friction damper made of steel plate and aluminum plate could be accurately simulated with the so-called perfect elastic-plastic model without degradation in stiffness. It has also been verified that the seismic performance of the composite structures could be accurately predicted if one use the perfect elastic-plastic model to simulate the behavior of the connecting friction damper. In addition, the tests have shown that the use of friction damper to connect an existing unfit concrete building and a new steel building could effectively reduce their displacement response and acceleration response simultaneously. The mitigation degree due to the friction damper on the seismic response of the composite structures depends upon the relative stiffness of the two buildings, the natural periods, and the mass ratio of the two buildings.
