Associating with the typical teaching building in 5·12 Wenchuan Earthquake disaster area of Sichuan Province,the interaction performance between frames and stairs was explored.The interests cover the static lateral stiffness of the static single frame unit,the lateral stiffness of the whole frame,the dynamic performance of the whole frame,the responding analysis under the standard earthquake spectrum of current Chinese code,and the calculation of time history under different earthquake records.The results show that the existence of stairs greatly affect the lateral stiffness of frame,dynamic performance,the peak of internal forces under standard earthquake spectrum of current Chinese code,and the peak of internal forces and node response spectrum under different earthquakes.These can be used as necessary references for the construction and strengthening of the similar buildings in disaster area.
