Earthquake resistant design for the school buildings have become an important issue as a lot of school buildings had been collapsed in the wake of the current Sichuan Province earthquake reaching a magnitude of 7.9 on the Richter Scale having been brought about in China in May, 2008, claiming a lot of human lives.

Maintaining safety for the school buildings is important more than anything else as these buildings are an open space for the students to spend most of their time there for school learning and for playing a role of providing emergency shelters against earthquake, typhoon and flooding for the regional citizens as well.

In addition, a new earthquake resistant renewal plan for the school buildings considering learning environment at the same time is required as an open space meeting the requirements of diversified learning patterns is called for as a result of introduction of a new educational method breaking away from the existing classroom patterns while maintaining earthquake resistant safety elements.

Currently, by the suggestion of several new vibration control systems, study on the quantification featuring energy absorption characteristics and the evaluation for the vibration control characteristics of the structures equipped with vibration control system is being progressed extensively. In addition, along with increase of the buildings equipped with diversified vibration control systems, this system is being widely utilized on a gradual basis for the purpose of earthquake resistant renewal and reduced earthquake response to be applied for the existing buildings as well as the newly constructed buildings.

Friction damper, a part of this system, has a high seviceability as this component is cheaper and highly reliable, without temperature dependability of attenuation performance or frequency dependability. Furthermore, design freedom for the designers could be expanded at the time of designing interaction vibration control structures since magnitude of initial strength or yield strength could be adjusted depending on the magnitude of applied tension.

Therefore, in this study, a interaction vibration control system is suggested for the school building renewal based on the difference of displaced response of the adjacent two buildings by utilizing friction dampers with a view to verifying earthquake resistant performance of the suggested interaction vibration control system.
