CONSTITUTIVE MODEL FOR BOND DAMAGE IN SRC STRUCTURES
-
摘要: 型钢与混凝土之间的粘结损伤是一个非常复杂的过程,其损伤机理很少有人研究。将概率引入损伤的定义,首次提出了基于概率统计的型钢混凝土粘结损伤本构模型;并用两个推出试验展现了型钢混凝土粘结损伤的发展演化过程。Abstract: Bond damage in steel reinforced concrete(SRC) is very complicated,whose mechanism is seldom studied as yet.Probability is introdu ced to define damage,based on which a new constitutive model of bond damage in S RC is proposed,and the push-out test result is used to demonstrate the course o f damage.
