Research data supporting "Deep embedment strengthening of full-scale shear-deficient reinforced concrete beams"

The beams had an effective depth of about 600 mm, a shear span to effective depth ratio of about 3.0, and were reinforced with internal steel shear reinforcement. The deep embedment (DE) shear strengthening system consisted of six 12 mm diameter sand-coated glass fibre reinforced polymer (GFRP) bars in each shear span.

The DE GFRP bars enhanced the shear force capacity of the strengthened beam by about 96%. The strengthened beam had a slightly higher cracked stiffness due to the presence of the DE GFRP bars which resisted inclined crack opening and consequently controlled deflection. The main shear crack in the strengthened beam had a steeper inclination.
