| The structural analytical method of elastic-plastic earthquake responses can be separated into macroscopic method and microscopic method. The microscopic method can be named finite unit method. This method is prefect, but use large numbers of computer-time. It is difficult to exert to the analysis of frame-wall structures. So we can only use macroscopic method to analyze the time-history of frame-wall structures. Advanced a sort of macroscopic model perfectly for R/C frame-shear wall structures is the intention of this paper. Then the author make the nonlinear analysis of R/C frame-shear wall structures.The author analyzed the macroscopic finite unit models for R/C shear wall and column at present time in the world. The ubiquitous localization of R/C shear wall is that we considered buckling-destroy occurred first, and then shearing-destroy occurred for the R/C shear wall. So we can consider separately the change of shear stiffness and axial stiffness, and adopt different hysteretic model. In fact, the change of axial stiffness must arouse the change of shear stiffness. The author in this paper combine the effects of axial stiffness and shear stiffness to propose a more rational multi-component-in-parallel model, different hysteretic models are adopted to simulate the different characteristics of steel and concrete for axial stiffness.For validated the macro-finite element model for R/C shear wall presented here, Quasi-static tests of nine reinforced concrete shear walls are carried out under different axial compression ratio and shear-span ratio. Based on the experimental and analytical results, some conclusions with engineering significance can be drawn.Shaking table tests of three-story reinforced concrete frame-wall model is carried out and the test analysis are introduced in this paper. The programs are written used the macroscopic finite method for the nonlinear analysis of R/C frame-wall structures. Comparison between analytical results and the results of shaking table tests show that the calculated time histories of the frame-wall model are agreeable to the tested ones, the analytical theory and method that developed in this paper is reliable. Then the time-history analysis of symmetrical and dissymmetrical structures is carried out under the single and bidirectional seismic wave.Based on the above experimental and analytical results, some conclusions with engineering significance can be drawn as follows:(1) With the increase of axial compression ratio to some range, the bearing capacity of shear wall will increase if the shear span ratio of walls is the same, while the ductility will descend and degradations of strength and stiffness are also more serious.(2) The shear span ratio is an important factor for the disruptive form of shear wall. If other parameters are the same, the destructed behavior of shear walls will be changed from the shear failure to bending failure with the enhancement of shear span ratio. And the bearing capacity will fall, while the ductility and capability of consuming energy will be strengthened.(3) For the walls of shear failure, the stiffness and carrying capacity quick fall when the stiffness and load are not degenerate sharply in the displacement control loading stage, this instance should be avoided in engineering design; For the wall of flexural failure with good ductibility and energy dissipative capability, the stiffness and carrying capacity fall slowly, this instance should be adopted in engineering design.(4) For the choice of hysteresis loop model, three-linear model of sloping stiffness degradation and two-linear model of sloping stiffness degradation are suggested to the smaller shear span ratio, and three-linear model of even stiffness degradation is suggested to the larger shear span ratio.(5) With the development of crack and plastic distortion, the frequency of every model is degressive and the speed of decline for first frequency is the fastest. At the same time, damping of every model is increased.(6) The dissymmetry of the structural members for resisted the lateral load will make the structure rotate because the center of mass apart from the center of stiffness. The retortion will increase the burden of members on the edge of structure, especially the comer column should be noticed.(7) The nonlinear time-history analytical method for frame-wall structures is developed, in which "a member-story model" is used as the dynamic analytical model for the whole structure. Macro-finite element models are adopted for R/C column and shear wall, different restoring performances are used to simulate the different characteristic of steel and concrete. Comparison among analytical results microcosmic finite element method and the results of shaking table tests show that the nonlinear analytical method developed in this paper is reliable.(8) The bottom of structure should be strengthened because this part is unsubstantial for the displacement corner is maximal.(9) Compared with the structural response under single seismic wave, the displacement and comer increase under bidirectional seismic wave. This phenomena is distinct at tile top ofstructure than at the bottom of structure. The period of structure is increased appreciably and the time of maximal peak value is delayed in a way.(10) The effect for horizontal displacement is limited if the prejudicial distance is smaller, the effect for horizontal displacement should increase if the prejudicial distance is larger. The burden of fringe members are added for the increase of prejudicial distance, and the fringe members are dangerous, so members should be disposed symmetrically.(11) The symmetrical and dissymmetrical structures are sensitive for the change of damp ratio, the top of structure is sensitive than the bottom of structure. The key of logical design is the reasonable choice of damp ratio.(12) With the increase of mass, inertial force will enhance, The period of structure will increase, displace and corner will enhance. So the increased load should be considered for structural design.
