This study analyzed on the basis of high-rise in the elastic structure, coupled shear walls added later, when subject to lateral force, the obtained shear bear axial force, lateral deflection, bending moment, shear, etc. ... mechanical properties, and to explore the coupling of shear deformation on the lateral inhibition effect, and when the parameters change its corresponding relationship. The method is based on research with the center of the beam as a benchmark, the establishment of conditional harmonic distortion and force - displacement relationship, in the solution of simultaneous equations, you can find the wall of the analytical solution, and then do numerical analysis .
