| Reinforced concrete masonry shear wall structure is a new type of structure,the theory of computing and analysis for it is juvenility. Microcosmic nonlinear finite element was used to analysis the stress performance of Reinforced concrete masonry shear wall structure. The main work carried out goes as follows:(1) The principal theory of nonlinear finite element analysis was expatiated and a new finite element compute model was advanced based the principal theory and the new model. A program with C++ language was designed to calculate ultimate load of the reinforced concrete masonry shear wall structure. The reliability of the program was proved by comparing the program results with experimental results.(2) Using the program, impact to the shear resistant of the ratio of grout for concrete and the ratio of height to section thickness and the horizontal reinforcement ratio was discussed. The limited range ordinate by the Code for design of masonry structures was validated.(3) Using the program, impact to the compressive strength of ratio of grout for concrete and ratio of height to section thickness to the compressive strength was discussed. A new formula was advanced in this article.
