Structural repair of shear-deficient reinforced concrete beams using SIFCON

摘要

This article reports on the structural behaviour of shear-deficient reinforced concrete beams repaired with Slurry Infiltrated Fibre Concrete (SIFCON), and proposes a simple analytical procedure for predicting the shear capacity Of the repaired beams. SIFCON is made by pre-placing short, discontinuous steel fibres into the form, followed by Infiltrating the fibres with cement-based slurry. A series of 14 shear-deficient reinforced concrete rectangular beams Was tested under third-point loading to study the effectiveness of using externally applied SIFCON jackets as a Method of increasing the beams' shear capacity.
