ABSTRACT = {This paper proposes a hybrid peridynamic and classical continuum mechanical model for the high-temperature
damage and fracture analysis of concrete structures. In this model, we introduce the thermal expansion into
peridynamics and then couple it with the thermoelasticity based on the Morphing method. In addition, a
thermomechanical constitutive model of peridynamic bond is presented inspired by the classic Mazars model
for the quasi-brittle damage evolution of concrete structures under high-temperature conditions. The validity
and effectiveness of the proposed model are verified through two-dimensional numerical examples, in which the
influence of temperature on the damage behavior of concrete structures is investigated. Furthermore, the thermal
effects on the fracture path of concrete structures are analyzed by numerical results.},
