Seismic Fragility Analysis of Reinforced Concrete Frames Based on the Service Age Variation

摘要：

　　The seismic fragility of R/C frames was redefined as the conditional failure probability of the structure with regard to the ground motion index and structural service age in this paper.An analytical method was proposed to disclose the seismic fragility variation of reinforced concrete frames with respect to the service age.Considering the variation of nonlinear mechanical characteristics of un-carbonated concrete within the service life, the seismic fragility variation of frames was analyzed using the inter-story drift ratio in the weak storey.For the defined damage levels of frames, each seismic fragility curve variation reflects the failure probability change tendency within the service life.A R/C frame was modeled to illustrate the variation of the seismic fragility within the service life.
