The work presented in this paper investigates the causes of size effects in structural-concrete members. It is
based on the use of a finite-element model found to yield realistic predictions of structural-concrete behavior in all
cases investigated to date. In fact. the previous use of this model in investigations ofsize effects in reinforced-concrete
beams indicated that such effects reflect the dependence of load-carrying capacity on small unintended eccentricities
of the applied load and/or load-induced anisotropy. rather than. as widely considered, on fracture-mechanics
characteristics. The present work extends the scope of the above investigation so as to include the case of reinforced
concrete flanged shear walls. the behavior of which is already established experimentally. It is found that. unlike the
flanged shear walls with a height-to-length ratio larger than 2. the shear walls investigated in the present work. in
contrast with the interpretation given to recently published experimental findings. are size-effect independent.
