In order to have a clear understanding for frame structure's vibration modal, and improving the structure's dynamic characteristics. This paper adopts finite element method to simulate and calculate frame structure teaching building, and gets natural frequency and vibration mode of frame structure teaching building, and analyses and explain calculation results. Analysis results show that the frame structure buildings is economic and reasonable, can satisfy the engineering requirement. The results showed that, the first and second order vibration mode of teaching building structure is translational vibration mode, and the upper vibration mode is main, the dynamic characteristics of teaching building structure are more complicated, the vibration modal of teaching building structure are mainly translational in the process of vibration, teaching building structure's transverse stiffness is minimum, the longitudinal stiffness is more smaller, The vertical stiffness is maximum.
