Abstract

The analysis and design methods based on energy not only is clear in concept and simple in form, but also better reflects the intensity of ground motion, spectral characteristics, in particular structural cumulative damage failure caused by the duration of strong earthquake. Therefore, seismic response analysis based on energy has been increasingly paid concern by domestic and international earthquake engineering research community, and some progress of this field has been made. Considering changes of ground motion factors changing law of total input energy and its distribution and structural dynamic properties, of plane frame structure for different damping model is analyzed, and then it is obtained that the difference using of the total input energy and its distribution as a result of different damping model selection, reaching a preliminary understanding of these quantitative and qualitative differences in the law. A new method was proposed to compute the damping coefficients in linear dynamic analysis. The method is verified by comparing to the mode-superposition approach.
