Structural analysis | Bond properties between corrosion resistant reinforcing steel and concrete.
This research program aimed to identify differences in the bond characteristics of corrosion resistant steel bars embedded in concrete relative to standard ASTM A615 reinforcing steel.
An experimental program was conducted where reinforcing steel bars were embedded in blocks of concrete and then pulled out while recording tensile load and bar slip
Beam End Test Specimen Dimensions and Details:
The typical beam end test specimen is a 24 in. by 11.25 in. by 9 in. concrete block with a reinforcing steel bar embedded as shown in Figure 11. Grouped forms were constructed out of 0.75 in. thick plywood and 2 in. x 12 in. boards, such that 1 form could hold 9 individual specimens.
The reinforcing steel was embedded in the concrete with a bonded length, Le=4 in. The short bonded length, achieved by embedding the majority of the bar in 1 in. diameter polyvinyl chloride (PVC) pipe, was employed to encourage a pullout failure of the bar from the concrete before bar yielding.
that preliminary tests documented in Johnson (2010) demonstrated that for Le 5 in. the steel yielded before bar pullout for the #4 bars. The experiments described in the following sections demonstrate that even with Le=4 in. that many of the #4 bars failed by yielding, an unexpected result.
Beam End Test Frame Details:
The beam end tests were performed with the structural loading frame
The frame provided a self-equilibrating reaction for a 50 kip MTS tension/compression servo controlled hydraulic actuator that pulled on the test bar embedded in the beam end specimen
The moment frame was flanked by two W21x55 beams anchored to the structure’s lab reaction floor.
A steel C8x13.75 beam spanned between the W21x55 beams and served as the lateral compression reaction at the top of the beam end specimen
A steel 4x4x¼ square HSS section served as the bottom lateral compression reaction. A built-up steel angle spanned between the W21x55 floor beams to provide the compression reaction across the top of each specimen
The compression brace was anchored to the floor beams with two 1 in. diameter A325 bolts tightened to a torque of 80 lb·ft. with an impact wrench
Relative Rib Area and Load-Slip Response:
Although the primary focus of this study was to explore the load-slip behavior between CRR bar types, the testing results have made it clear that relative rib area is the most influential parameter affecting load-slip response
Another important observation from this study was that stainless steel had on average a lower bond stiffness than A615 steel when comparing bars with similar relative rib areas.
Another important observation from this study was that stainless steel had on average a lower bond stiffness than A615 steel when comparing bars with similar relative rib areas.
Effect of Epoxy Coating on Load-Slip Response:
The load-slip response clearly demonstrate that the Zbar epoxy coating reduces the chemical adhesion between concrete and the reinforcing steel, however the presence of epoxy does not influence the mechanical bond stiffness and bond strength when comparing A615 bars with similar relative rib areas.
