Dynamic Rest Research On Seismic Performance For Frame Retrofitted With Hybridized CFRP

According to the experience of the earthquake which causes damage to the structure,the destruction of the frame structure form is "strong beam weak column" more, therefore,building structures collapses. So the researchers seek solutions. For example, increasingthe damping: shocking isolation reinforcement, reinforcement, Improving the bearingcapacity: a wall reinforcement and supporting wall reinforcement, reinforcement columns,Improving the stiffness: wall reinforcement, reinforcement wall, To improve ductility:strengthening column, slotting reinforcement and so on. The epicenter "strong beamweak column" form of damage to structure is the most severe. Therefore, it hopes thatitshifts the failure mechanism through carbon fiber reinforcement,and it reduces thebuilding’s demolition. Because of the large elastic modulus of carbon fibers, high tensilestrength, good fireproof limit, and convenient,quick construction, thus which are adaptedto reinforcement of the Civil engineering.Through two dynamic loading test of the specimens, which research the yield ofcolumn and beam before and after reinforcement mechanism, and analyze the slabreinforcement stress, along with the change of different distances, and the comparison ofreinforcing plate before and after reinforcement. At the same time, analysis of thestructure of the whole energy dissipation, stiffness degradation, ductility coefficient.Based on experimental research, which carry out the simplified model of the framecolumn reinforcement design and calculation analysis, analyzing the critical bearingcapacity and the change of the stiffness matrix after reinforcement. From the test point ofview, yield beam hinge mechanism achieves; energy consumption increases; the stiffnessdegradation slow down; Ductility coefficient is reduced, but also which meets therequirements of ductility coefficient. From the theoretical point of view, the criticalbearing capacity was improves; the stiffness matrix, horizontal bearing capacity isimproved.
