Double Parameter Seismic Damage Model of Concrete-filled Rectangular Tubular Column

摘要：

In order to establish the double parameters earthquake damage model of concrete-filled rectangular tubular (CFRT) column, the hysteretic behavior of CFRT column under a constant axial load and cyclically varying lateral loads was utilized to obtain cumulative damage. Moreover the double parameters earthquake damage model that was fit for CFRT column has been set up by regression analysis .The results showed that the energy weighted coefficients of CFRT columns damage were and . The model for CFRT columns and damage analysis has a great significance to seismic design and earthquake damage prediction.
