The time dependent structural analysis method
under multi actions in consideration of drying shrinkage due to moisture transfer
and re-bar corrosion due to chloride ion penetration as well as external load actions
was developed. The Rigid-Body-Spring Networks (RBSN) and truss networks model were
used for structural analysis and mass transfer analysis, respectively. In addition
to, mass transfer through bulk concrete, the one through cracks by setting truss
networks on the boundaries of Voronoi particle was also considered. It was confirmed
that the developed method was well simulated the deterioration process due to mass
transfer for initial cracking behavior and ultimate behavior of concrete structures.
