- Abstract
A new type of energy-dissipated structural system for existing buildings with story-increased frames is presented and investigated in this paper. In this system the sliding-friction layer between the lowest increased floor of the outer frame structure and the roof of the original building is applied, and energy-dissipated dampers are used for the connections between the columns of the outer frame and each floor of the original building. A shaking table test is performed on the model of the system and the simplified structural model of this system is given. The theory of the non-classical damping approach is introduced to the calculation analyses and compared with test results. The results show that friction and energy-dissipated devices are very effective in reducing the seismic response and dissipating the input energy of the model structure. Finally, the design scheme and dynamic time-history analyses of an existing engineering project are investigated to illustrate the application and advantages of the given method.
