Types of Rebar Applications
Post-installed reinforcing bars are typically used to develop a monolithic connection between new and existing concrete elements or structures. Post-installed reinforcing bars are used in both retrofit work and in new construction and are suitable for a wide range of applications. Let’s look at some of the common rebar applications below.
IMPORTANCE OF DESIGN
To ensure that the post-installed reinforcing bar behaves as a cast-in bar, it is important that the type, size, spacing and quantity and anchorage be established for the connection. This is typically based on either direct calculation of section forces, or a requirement to match existing reinforcement. Hence, design of rebar connections are important to achieve desired results.
The rebar applications mentioned above can be clustered into 3 categories and have different design requirements.
End anchorages involve connecting new concrete elements perpendicular to existing ones. Examples include beam-to-column, slab-to-wall, column-to-foundations, and so on.Know more about End Anchorages
Lap splices involve extending existing concrete elements parallel to existing ones. The new bars are not in contact with existing ones. Examples include beam extension, column extension, slab extension etc.Know more about Splices
Concrete overlays involves increase the cross-sectional thickness of an existing member by connecting a new layer. Examples include beam jacketing, column jacketing, slab strengthening etc.Know more about Concrete Overlay
