Shear strengthening of reinforced concrete members with CFRP sheets

[EN] In light of their excellent mechanical properties and other advantages over conventional systems for repairing and rehabilitating structures, fibre-reinforced polymers (FRPs) are commonly used to enhance the shear strength of RC members. Because of the relatively recent application of the techn...

Sin embargo, debido a que su uso es relativamente reciente en la ingeniería civil, existen pocas recomendaciones o guías que consideren esta técnica. Las guías de cálculo existentes muestran un procedimiento bien definido y aceptado con respecto al cálculo a flexión, sin embargo, los modelos de cálculo a cortante resultan ser altamente variados y controvertidos. Este documento muestra el enfoque actual para el cálculo de esfuerzos cortantes y sus limitaciones, así como el proceso de una investigación experimental sobre vigas de hormigón armado reforzadas externamente con tejido unidireccional de CFRP.Peer reviewedCSIC - Instituto de Ciencias de la Construcción Eduardo Torroja (IETCC)Consejo Superior de Investigaciones Científicas [https://ror.org/02gfc7t72]2013201320132013info:eu-repo/semantics/articlehttp://purl.org/coar/resource_type/c_6501http://hdl.handle.net/10261/79783reponame:DIGITAL.CSIC.
