Abstract
This paper presents a numerical model for simulating the nonlinear
response of reinforced concrete (RC) shear walls subject to cyclic
loadings. The material behavior of cracked concrete is
described by an orthotropic constitutive relation with tension-stiffening
and compression softening effects defining equivalent uniaxial stress-strain
relation in the axes of orthotropy. Especially in making analytical
predictions for inelastic behaviors of RC walls under reversed cyclic
loading, some influencing factors inducing the material nonlinearities
have been considered. A simple hysteretic stress-strain relation
of concrete, which crosses the tension-compression region, is defined.
Modification of the hysteretic stressstrain relation of steel is
also introduced to reflect a pinching effect depending on the shear
span ratio and to represent an average stress distribution in a cracked
RC element, respectively. To assess the
applicability of the constitutive model for RC element, analytical
results are compared with idealized shear panel and shear wall test
results under monotonic and cyclic shear loadings.
