Abstract：On the basis of cast-in-situ shock-absorbing stairs，a prefabricated stairwell was developed. A comparison test on the seismic performance of general stairs and energy-dissipating stairs was carried out and the structure and shock-absorbing principle of the prefabricated energy-dissipating stairs were introduced. A method to improve the seismic performance of the stairwell structure was proposed，and stair units of different structures were made to form a prefabricated energy-dissipating stairwell. The results show that the seismic performance of the prefabricated stairwell with energy dissipation structure has been improved.
