ABSTRACT

Different from the traditional seismic design method based on bearing capacity and displacement, the energy method can consider the cumulative plastic damage caused by earthquake duration, which is a relatively perfect seismic design method and has attracted wide attention. Based on the principle of energy balance, through the analysis of hysteretic energy consumption and its interlayer distribution, we can find out the weak parts of the structure and make an effective qualitative evaluation of the seismic performance of the structure. By calculating the inter-story damage index of the structure, the seismic performance of the frame structure can be effectively and quantitatively evaluated. Example analysis shows that the energy response distribution of the structure is closely related to the selection of damping model, and the seismic response and damage process of the structure are closely related to the energy absorption and dissipation process of the structure.
