SHAKING TABLE TEST ON A LARGE STORK HEIGHT MOMENT FRAME

Due to the architecture function restriction，it is difficult some large scale public buildings to use the traditional strengthening methods，hence only partia stories could be equiped with dampers when using energydissipation method． This paper concentrates on a shaking table test of a moment frame structure public building model． This structure only installed the viscous dampers can be installed only on weak layers． This paper compared the seismic response and dynamic character of the model with and without damper． The test result shows that installing the viscous damper on weak layer is effective in controlling and decreasing seismic response．
