To rapidly evaluate the seismic resilience of the bridges under construction, the construction stage seismic resilience evaluation method was proposed. Based on a case bridge of continuous girder with the cast-in-place cantilever construction method, the seismic resilience of bridges at different construction stages was researched and compared. The bridge model was established by utilizing the construction stage module in the Midas Civil finite element modelling software. The functional losses of the bridges at different construction stages were computed. The three dimensional functional surfaces of Function-Time-PGA (Peak Ground Acceleration) were drawn. The resilience indexes at different construction stages with different seismic PGAs were compared, the resilience indexes with and without consideration of the delay recovery period were compared and analysed. The research results show: 1) in the control period, the functional loss is directly proportional to the PGA, but the function and resilience indexes are inversely proportional to the PGA; 2) the seismic resilience indexes of bridges at different construction stages are vastly different; 3) the resilience indexes with and without consideration of the delay recovery period are different; for the case bridge with the delay recovery period to recovery period ratio of 20%, the difference of the resilience indexes with and without consideration of the delay recovery period can reach 17% when the seismic PGA is 1.0 g. This paper provides a new method to evaluate the seismic resilience of construction stages, and it can be used to provide suggestions for the seismic damage evaluation and post-seismic recovery scheme.
