Definition Of

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.

Reinforced Concrete Chimney

Through calculation and analysis on routine examination and neutralization of reinforced concrete chimney, the service life of concrete structure was evaluated only considering neutralization of concrete single factor. The results show that the neutralization of the reinforced concrete chimney was serious than that of other similar projects. The initiation time of reinforcement corrosion were 19.3a, cracking time of concrete cover were 27.35a.
