Being a kind of framework material, framework interstice concrete is composed of single-grade or gap-grade aggregate which are bonded by cement or bitumen, whose structural characteristic is \“bonding crunode + aggregate + space”. This paper develops a kind of micromechanical model, carrying out numerical simulation of flexual performance of the framework interstice concrete. The calculating results basically conform to the experimental result gained in the laboratory. The method discussed in the paper can be developed to apply in calculating analysis on all kinds of framework interstice concrete materials. Keywords: framework interstice, framework interstice concrete materials, micromechanical model, numerical simulation.
