摘要
A test apparatus used for simulating debonding between a carbon fiber reinforced polymer (CFRP) and concrete in a CFRP-strengthened structure consists of a primary structural block, a secondary structural block, an adjustable hanger, a receiving slot, an attachment mechanism, a pull-off disk, a connecting plate having a plurality of rods. The adjustable hanger and the secondary structural block are slidably positioned into the receiving slot that traverses into a structural body of the primary structural block. The adjustable hanger is mainly used during double-shearing tests and mixed-mode tests, wherein both shearing and peeling is analyzed in mixed-mode tests. The secondary structural block is used in double-shear tests, mixed-mode tests, single-shear tests, tension pull-off tests, and beam-bend tests. The attachment mechanism, which holds the primary structural block, the secondary structural block, and the adjustable hanger together, is also used during single-shear tests and beam-bend tests.
