Abstract

An analysis on the seismic risk assessment of reinforced concrete bridges is made in this paper, which considered the random time-dependent strength both of the concrete and reinforced bars in the design working life. The seismic risk curve of bridges in the design work life is formed under the given design basic acceleration of ground motion. According to the obtained risk curve, it is possible to make forecast on the seismic risk of bridges in the working life under the seismic fortification intensity.
