At present, reinforced concrete finite element method, as an effective numerical method has been widely applied and is officially listed as one of the design approaches for non-member reinforced concrete structure reinforcement in Design Specification for Hydraulic Concrete Structure. Finite-element pre-and post-processing is a bottleneck for the finite element method application and development so researches on it are of significant importance. This paper adopts the embedded VBA language development tool of AutoCAD to compile finite-element pre-and post-processing application software for plane reinforced concrete based on the nonlinear finite element analysis program conducted by Hohai University’s Civil Engineering department, which realizes visualization and finite element analysis program as well as seamless integration of CAD. Users can quickly and reversibly carry out finite element modeling with visual graphs according to the design paper and the result is output based on requirement. This paper sums up with the ideas to take relevant segments automatic k-mesh generation technology to form element topology and improve the flexibility of finite element modeling.
