It is</p><p align="left">based on the use of a finite-element model found to yield realistic predictions of structural-concrete behavior in all</p><p align="left">cases investigated to date. In fact, the previous use of this model in investigations of size effects in reinforced-concrete</p><p align="left">beams indicated that such effects reflect the dependence of load-carrying capacity on small unintended eccentricities</p><p align="left">of the applied load and/or load-induced anisotropy, rather than, as widely considered, on fracture-mechanics</p><p align="left">characteristics. The present work extends the scope of the above investigation so as to include the case of reinforced</p><p align="left">concrete flanged shear walls, the behavior of which is already established experimentally. It is found that, unlike the</p><p align="left">flanged shear walls with a height-to-length ratio larger than 2, the shear walls investigated in the present work, in</p><p align="left">contrast with the interpretation given to recently published experimental findings, are size-effect independent.</p></font></font> Flanged shear walls; Nonlinear analysis;Finite-element; Reinforced concrete; Size effects 27 40 http://ijce.iust.ac.ir/browse.php?a_code=A-10-451-7&slc_lang=en&sid=1 Alireza Mortezaei 180031947532846006050 180031947532846006050 No Ali Kheyroddin akheirodin@semnan.ac.ir 180031947532846006051 180031947532846006051 Yes
