Analysis of the composite wall with steel frame shear deflection of the micro numerical strength, has important significance in improving strength and seismic performance of composite wall with steel frame in civil engineering. In order to improve the strength and seismic performance of buildings, and analysis of the composite wall with steel frame shear de-flection of micro numerical strength, grasp the structural damage analysis of constructing incentive, stress damage model of reinforced concrete column under the shape structure, improving construction of strong rigidity, reduce the lateral load side surface has an important role. Micro numerical analysis using ANSYS software, the mechanical model of construction body is obtained. Steel structure and steel- concrete composite structure deformation modulus is loaded by FIP90 curve and Hongnestad constitutive relation model, this mechanism analysis of composite wall with steel frame and creep of generation and load distribution of the concrete structure, using the stress-strain relationship of dynamic model of curvature correction response surface method, the realization of micro analysis on the shear strength of numerical immunity. The experimental analysis, the model of the numerical analysis is accurate, through microscopic numerical accurate analysis of shear wall, grasp the disturbance degree and mechanical performance, it can provide the data basis for building construction.
