Abstract:The staircase serviced as a passage for evacuation and rescue of buildings during earthquakes. Its seismic and energy dissipation design should attract sufficient attention from the civil engineering community. The basic structural characteristics and design theory of the staircase were introduced. The related research on  seismic and energy dissipation technology of the staircase was summarized. The seismic damage, test, numerical analysis and specification were discussed respectively. The problems existing in the current research were discussed and the further researches were advanced.

Keywords:staircase; seismic and energy dissipation technology; structure; research status
