An analytical method to obtain the seismic fragility curve of reinforced concrete frames with service life was proposed in this paper. Considering the variation of nonlinear mechanical characteristics of un-carbonated concrete with service life, the seismic fragility curve of frames was developed based on the interstorey drift corner in the weak storey of frame structures. According to the damage state definition of frames, each seismic fragility curve reflects the probability tendency of the defined damage state happening in frames with service life. It is helpful for the seismic performance analysis of reinforced concrete frames to use the proposed method.

An analytical method was proposed to obtain the seismic fragility curve of reinforced concrete frames within the service life. Considering the variation law of nonlinear mechanical characteristics of un-carbonated concrete within service life, the seismic fragility curve of frames was developed based on the inter-storey drift corner in the weak storey of frame structures. According to the defined frame damage states, each seismic fragility curve reflects the probability change tendency of the defined damage state in frames within service life. A numerical example was modeled to illustrate the variation characteristic of seismic fragility within the service life.

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.
