DEFORMATION CAPACITY OF UNBONDED POST-TENSIONING MONOSTRAND ANCHORAGES UNDER MONOTONIC AND CYCLIC LOADING (PART 2: MONOTONIC LOADING TEST RESULTS)

摘要

According to the test results the following conclusions can bederived: All the samples showed ultimate strength larger than0.95fpu. However, due to the fracture of only one or a few wires, allsamples were not able to develop their full capacities. In general, CPanchors showed better ultimate capacities than BL anchors.Ultimate strain capacity was found to be between 4.4-4.7% in CPand 1.5-4.0% in BL. The maximum wedge seating was found to bebetween 6.6-7.5mm in CP and 6.2-6.7mm in BL.
