Dynamic time-history analysis of the vibration energy dissipation frame

The damping frame structures have a variety of vibration-absorbing forms such as mass dampers,base isolators and damping energy dissipation.In this paper,the damping frame structures with energy dissipation braces are considered.The dynamic model for the vibration-isolating frame is established and the dynamic equation of the system is obtained.By using universal finite element analysis software ANSYS,the linear time-history seismic analysis for the frame is carried out.The comparison of dynamic responses between energy dissipation frame and anti-seismic frame structure are presented.It can be seen from the numerical results that the energy dissipation structure has obvious vibration-absorbing effect.
