| The short pier shear wall system is a kind of new type structural model of high rise-building; this thesis introduces the history and situation at present of the development and study of short pier shear wall system, and the problems must be further study on short pier shear wall system are analysed, the main task will be take in this thesis is introduced.Firstly, this thesis introduces the methods about the calculation of short pier shear wall, and analyzes this result of calculation, at the same time points out the influences of integrate and pier strength coefficients and radio of section to width. Some suggestions for engineering design are also presented in this paper.Secondly, the element stiffness matrices of plain-plate are reduced, and the thesis applies it to the structures of short leg walls, and sums up the feasibility and advantage of this finite element. Later, the theorization of non-linear finite element analysis on reinforcement concrete shear wall is presented, and the program of finite element is worked out.Thirdly, the author utilized MATLAB computer langue compiles calculate program, and the instance analyzes was taken .Based on plain-plate finite element model, the ductility analyses of short pier shear walls with different pier strength coefficients, integrate coefficients, flange widths of piers were implemented. The influences of these parameters were studied, and the results indicate that with the increase of pier strength coefficients and integrate coefficients, the load capability of short pier shear wall decreases, however its ductility of increases on condition that the cross sections keep constant. In addition, with the increase of flange width of piers, both the load capability and ductility of the wall increase. The calculate results manifest the new method is valid and reliable.At last, on the basis of analysis result, the conclusion is drawn and the useful recommendations and perspectives were put forward.
