ANALYSIS OF INTERRUPTABLE HEIGHT OF SHEAR WALL IN FRAME-SHEAR WALL STRUCTURE

Based on the relationship among axial force–bending moment–curvature of reinforced concrete member section, the nonlinear finite element method considering P–Δ effect and shear deformation was established which was able to analyze the ultimate state. Regarding the shear wall as special beam elements, the frame-shear wall structures with shear wall interrupted at different heights, with different reinforcements, axial compressive ratios and rigidity characteristics were analyzed. The conditions of interruptable shear wall height are proposed. Calculation results indicate that the decisive factor influencing interruptable relative height above the shear wall is the top displacement; the relative height is not related to reinforcements and axial compressive ratios, and slightly related to structure height. With the increase of the rigidity characteristic, the relative height increases. The equation between them is proposed.
