摘要:In this paper,based on the plastic - danage nodel proposed by Lee and Fenves and related algorithns,we develop the progran to sinulate the danage process of concrete structure subjected to cyclic earthquake excitation. To sinulate the phe-nonenon of stiffness degradation and recovery during a large crack opening and closing process,a critical tensile plastic - danage variable is defined to correct stiffness degradation variable and prevent excessive increase in plastic strain. A visco - plastic nodel is used to regularize this plastic danage nodel to reduce the dependence of conputational result on nesh size. According to the response of concrete specinen under different loading conditions and the danage evolution process of Koyna dan subjected to earthquake loading,the rationality and effectiveness of the presented nodel and the related progran is proved.
