Seismic Performance Analysis Of Reinforced Concrete Frame Structure Based On Pushover

China is one of the most disasterous countries which suffer from earthquakes. The intense earthquake brings serious harm to people’s life and property, these disasters are mainly caused by destruction from the buildings with low-quality seismic protective function. people understand that the raditional seismic design thought cannot satisfy the need for seismic protective function of modern building,the performance based seismic design was thought to be a main development direction in the seismic design area. Pushover analysis is gradually deemed to an important method for the performance based seismic design. Currently,the method is widely in structure system to get it’s seismic performance.In this paper, a reinforced concrete frame structure with 7 floors is researched mainly from the following aspects:① the paper describes research findings about the pushover analysis method both at home and abroad is summarized,and the basical principle,the basic assumption,the lateral load pattern,the advantages and disadvantages,two method of the pushover analysis.② the paper describes traditional seismic design theory, three type of performance based seismic design method,and the advantage are described.③ The structure’s response spectrum analysis under the frequent earthquakes was analyzed in SATWE,the results show that the control parameters of the structures can meet the requirements of specification and also satisfy its fortification goal of "no damage under minor earthquake".④The structure’s push-over analysis under the rare earthquakes was analyzed in midas buliding the results show that the maximum displacement,the maximum inter story displacement angle,Plastic hinge state of the structure can meet the requirements of specification and also satisfy the fortification goal of “no damage under frequent earthquakes,repairable under occasional earthquakes,and no collspse under rare earthquake.Conclusion of this paper can hopefully be a reference for the design of reinforced concrete frame and evaluation of structure’s seismic performance.
