Earthquake Damage and Design Requirement of Stair in Frame Structure

Abstract:

In building structure, staircase is more complex and relatively weak. As an important emergency routes when earthquakes and other emergencies (such as fire, explosion, etc.) take place, stairs subject highly evacuation live or seismic load, destruction of the stair caused delay of evacuation and affected the commencement of rescue work, and produced serious injury or death. Investigation of Wenchuan earthquake damage also finds that many stairs broken before the main structure. In the current code for seismic designof building, seismic design advice of stairs was only given instructionally, and specific calculation methods and construction requirements were lacked. Based on the analysis of earthquake destroy of stairs in frame structure, this paper proposes some design requirements of stair.
