Influence of shear wall for framework-wall seismic behavior

Use of R/C shear wall as a vertical load to bear against the horizontal load of the structure,known as the shear wall structure system.The advantages of shear wall structure:large stiffness,good space overall,smaller vertex structure of horizontal displacement and story drift,which are able to meet the requirements of anti-seismic deformation.Therefore,seismic performance of shear wall plays an important role on the shear wall structure and framework-wall structure.The number of shear wall impact structural stiffness.This article has been through the displacement mode eigenvalue stiffness-a relatively high point of anti-bending curve.
