Performance-Based Research of Existing Reinforced Concrete Building Structure Seismic Evaluation and Reinforcement Technology

Abstract:

Based on the current seismic codes, the elastic capacity calculation under frequent earthquake and ductile details of seismic design should be used for both seismic design of new buildings and seismic evaluation of existing buildings to satisfy the seismic fortification criterion, namely/no damage under frequent earthquake, repairable under moderate earthquake, and no collapse under severe earthquake0. For the evaluation, rebuilding and extending of existing structures which dissatisfy the ductile details of current seismic codes, the elastic capacity calculation under frequent earthquake is obviously not enough. In this paper, the advanced performance-based seismic theory is introduced while story drift ratio and deformation of component are used as performance targets to solve the problems of seismic evaluation and strengthening for existing reinforced concrete structures.
