INFLUENZA DEL DIAMETRO DEL FORO SUL COMPORTAMENTO IN COMPRESSIONE DI COLONNE IN C.A.

2012

Core-drilling technique is nowadays always more frequently performed in existing reinforced concrete (RC) structures in order to investigate on the mechanical properties of concrete and for structural health monitoring purposes. Even if the engineering practice discourages to drill columns, this can be often unavoidable. In this last case the presence of the circular opening influences the compressive behavior of the column in terms of load-carrying capacity and axial deformability. The goal of this investigation was the experimental evaluation of the effects induced by circular openings on the behavior of RC columns. 24 reinforced and plain concrete prisms in presence of circular openings …
