Abstract A novel coupled mechanical and mass transport lattice discrete particle model is developed to quantitatively assess the impact of cracks on properties in concrete members subjected short‐ long‐term loading conditions. In approach, two sets dual networks are generated: one resolve response another for analysis. The simulated by mapped onto elements investigate effect global members. new quantitative relationship proposed estimation diffusion coefficient based local crack information, capable describing both convection mechanisms. Moreover, creep behavior incorporated account influence induced Numerical results, form dynamic changes cumulative water chloride contents under tension, compression, bending with various stress levels show remarkable accuracy when compared available experimental observations. provides an effective means incorporating mesoscale information simulations varying
