WebThe bond-slip mechanism studied in this paper is based on experimental work done by Xu et al. (2024) [1]. The deformed rebar is well-confined concrete was monotonically loaded with a tensile force to form pull out test. The bond stress transfer at the interface between steel and concrete is represented by at least three mechanisms, WebJul 1, 2024 · 2.2.2 Pull-Out Tests. Pull-out tests are a simple and an inexpensive way to test local bond behaviour. However, they have two main disadvantages: (1) unlike real situations, the concrete is compressed while the bar is under tension, and (2) due to friction at the bearing end, they have greater resistance to splitting than is common in real … linea 2 tussam
