Shear Strengthening of Short Span Reinforced Concrete

2012-10-2  This paper presents the results of a series of tests on short span reinforced concrete beams which were strengthened in shear with various arrangements of externally bonded carbon fibre reinforced polymer (CFRP) sheets. The objective of the tests was to determine the effect of changing the area and location of the CFRP sheet within the shear span.

Strengthening of Short Shear Span Reinforced Concrete T

Twelve reinforced concrete (RC) T-joists strengthened with fiber-reinforced plastic (FRP) composites were loaded until failure in a short shear span configuration. Different strengthening schemes, including different FRP materials and a new FRP anchorage system, were adopted in order to compare the performance of the different installations.

2022-6-1  The most preferable, efficient and practised techniques for shear strengthening are RC jacketing and FRP wrapping [1]. However, using section enlargement with RC to enhance shear capacity, the thickness of the jacket, in typical cases higher than 70–100 mm, leads to the increased total mass of the structure and decreasing esthetics in architecture.
