In this paper, a multi-axial compression constitutive model of cement-based material subjected to combined alkali-silica reaction (ASR) and mechanical loading is proposed based on the plastic and damage theories. In this model, the elastoplastic behavior is coupled with the mechanical damage due to external loading and chemical damage due to ASR ex-pansion. The linear swelling rate of prism specimen is used to represent the ASR damage. A modified plastic yielding criterion and plastic potential function are introduced, taking into account the ASR damage on compression and tension properties. The proposed model is further verified by the tested stress-strain relationship under different confining pressures reported in a companion paper, and a good agreement is obtained.
