Some types of stair damage caused by Wenchuan Earthquake in frame structures were presented.The seismic response of stairs was studied by concept analysis and calculation.And how the stair-plate is broken and the stair-beam is destroyed were explained.It suggests that the effect of the earthquake on stairway should be analyzed by entirety structural model,which can be chosen to design the stair component.Some measures are proposed to guarantee the stairs capacity to resist earthquake.
