PREDICTION AND VERIFICATION OF SHEAR FORCE-DORIFT ANGLE RELATIONS FOR COMPRESSIVE BRACING SHEAR WALL WITH ARBITRARY WALL LENGTH

-Elastic and plastic behavior before buckling-

Abstract

Formulae to predict shear force-drift angle relations of compressive bracing shear walls with arbitrary wall length are proposed in this paper, taking into consideration the equilibrium of forces and friction acting on end of the braces. These formulae are derived assuming the major component of deformation of compressive bracing shear wall is the compression of both ends of a brace into a girder and a sill. These formulae are verified with element tests of brace ends and tests of bracing shear walls.
