In the most active earthquake areas in our country, the earthquake happened frequently inrecent years, our economic and property lost by the huge. And our country’s basic construction project has mainly from new to a new stage of new combined with renovation. Seismic strengthening has become a research focus now.In the framework of filling wall reinforcement is an effective seismic strengthening method, it avoids adopting strengthen components of stiffness and strength,on the one hand,it improves the shock resistance of the structure, on the other hand,it increas the safety of the structure of reserves. When filling wall seismic strengthening is adopted in our country, the wall decorates requirement is set in a row, at the bottom of the use function of the building will be badly affected. Learn from Japan’s experience in filling wall of seismic strengthening,we canmake filling under the seismic wall of discontinuous and study its reinforcement effect.According to seismic code and of scientific research of filling seismic wall strengtheningframe,using structural design analysis software ETABS program established a frameworkmodel of four layers which is arranged symmetrically and regularly in plane andelevation.The frame model don’t conform with the regulations of octave fortification. Firstlyusing continuous and malposed seismic walls to strengthen frame respectively. The seismicbehaviors of three models were studied by using mode-decomposition response spectrummethod and time-procedure analysis. According to the results of above analysis,it provedwhether the feasibility of using malposed seismic walls could be Enhance reinforcement.Secondly, using discontinuous seismic walls in space to strengthen initial framework model,according to the result of mode-decomposition response spectrum analysis, summarizingwhich arrangement in space of seismic wall is advantageous to strengthening. Finally,strengthen the framework by filling the seismic walls only in the weak story, and thestrengthen models do elastic-plastic analysis in under the effect of flame and smallearthquakes, According to the result of above analysis to validate the feasibility of that strengthen method.
