Earthquake Damage Model of Concrete-Filled Rectangular Tubular Column

Abstract. In order to establish damage model of concrete-filled rectangular tubular (CFRT) column, the paper utilized the cumulative dissipated hysteretic energy through 7 CFRT columns’pseudo static test. Moreover, the earthquake damage model based on CFRT columns has been set up by regression analysis. The damage model offers references for reinforcing the damaged structures caused by earthquakes and evaluating the ability of aseismatic of structures.
