With our country architecture industry's development, the high-rise construction appears unceasingly in our country. Our modern high-rise constructions have diverse structural style, the reinforced concrete frame-shear wall structure is one kind of structural styles which is used widespreadly in the modern architecture. It is one kind of structure systems, which collects frame and the shear wall characteristic to resist the horizontal lateral together. The purpose of the paper is to study frame-shear wall structural model, and the model has carried on the dynamic analysis by using the ANSYS software. Mainly including the following several aspects work:1. Establishing the structure model by using ANSYS, the earthquake responds analysis method is studied in the section. The frame-shear wall structure is executed the earthquake response analysis from different aspects, which contains the influence factor of the shear wall rigidity. The different shear wall rigidity's frame shear models are couducted the massive endogenic forces and the displacement analyses, and made compared to the practical engineering model.The main research content is carried on from the shear wall different rigidity's three aspects. Namely: The shear wall thickness's change, the shear wall quantity's change and the shear wall open the hole rate change.2. Conducting the modal analysis and the spectrum analysis to the frame-shear wall structure, the structure mode of vibration and the frequency are obtained through the modal analysis, the structure vibration characteristic can be seen clearly;Through exerting the different spectrum analysis to the structure, this thesis takes the partial shear wall and the frame column's nodal displacement value and the equivalent stress value's change, which provides some data reference for the structural design.3. Importing the different earthquake wave to the structure model, the structure is carried on the dynamic analysis by using the time history analysis method in the intensity of frequently ordinary earthquake. When the different horizontal earthquake wave effects the structure, this paper makes the massive analyses to the nodal displacement and stress of structure, and make a detailed comparative analysis to appear the biggest displacement's time of structure in different earthquake waves.Then, each time change situation of the structure is fully understood in earthquake function.
