Abstract EN
This paper presents the findings of an experimental study on the application of a reinforced self-compacting concrete jacketing technique in damaged reinforced concrete beams.
Test results of 12 specimens subjected to monotonic loading up to failure or under repeated loading steps prior to total failure are included.
First, 6 beams were designed to be shear dominated, constructed by commonly used concrete, were initially tested, damaged, and failed in a brittle manner.
Afterwards, the shear-damaged beams were retrofitted using a self-compacting concrete U-formed jacket that consisted of small diameter steel bars and U-formed stirrups in order to increase their shear resistance and potentially to alter their initially observed shear response to a more ductile one.
The jacketed beams were retested under the same loading.
Test results indicated that the application of reinforced self-compacting concrete jacketing in damaged reinforced concrete beams is a promising rehabilitation technique.
All the jacketed beams showed enhanced overall structural response and 35% to 50% increased load bearing capacities.
The ultimate shear load of the jacketed beams varied from 39.7 to 42.0 kN, whereas the capacity of the original beams was approximately 30% lower.
Further, all the retrofitted specimens exhibited typical flexural response with high values of deflection ductility.
