RESEARCH ON THE PERFORMANCE-BASED SEISMIC EVALUATION AND STRENGTHENING FOR EXISTING REINFORCED CONCRETE STRUCTURES
Based on the current Chinese seismic codes,elastic capacity calculation under frequent earthquake and ductile details of seismic design shall be performed for whether seismic design of new buildings or seismic evaluation of existing buildings to satisfy the seismic fortification criterion no damage under frequent earthquake,repairable under fortification earthquake,no collapse under severe earthquake. For the evaluation,rebuilding and extending of existing structures which dissatisfy with the ductile details of current Chinese seismic codes,elastic capacity calculation under frequent earthquake is obviously not enough. In this paper,the advanced performancebased seismic theory is introduced to solve the problems of seismic evaluation and strengthening for existing reinforced concrete structures,in which story drift ratio and deformation of components are used as performance targets. Some performance index of reinforced concrete structures and components are presented based on Chinese codes by taking American seismic codes for reference.
