Abstract:As an effort to meet the demands of retrofitting building structures after the Wenchuan earthquake, the seismic retrofit with attached substructures which has been widely used in Japan was introduced. Various types of attached substructures and their applications and effectiveness were demonstrated through typical retrofit projects. Design principles of structures retrofitted with attached substructures were proposed according to the requirement of the Chinese seismic design code.
Keywords:building structure； seismic retrofit； attached substructure； energy dissipating； deformation pattern
