After the 1999 Kocaeli Earthquake, the use of chemically bonded post-installed
anchors has seen a great growth for retrofits in Turkey. Currently, chemically bonded
post-installed anchors are designed from related tables provided by adhesive
manufacturers and a set of equations based on laboratory pullout tests on normal or
high strength concretes. Unfortunately, concrete compressive strengths of existing
buildings, which need retrofit for earthquake resistance, ranges within 5 to 16 MPa.
The determination of tensile strength of chemically bonded anchors in low-strength
concretes is an obvious prerequisite for the design and reliability of retrofit projects.
Since chemically bonded anchors result in the failure of concrete, adhesive-concrete
interface or anchored material, the ultimate resistance of anchor can be predicted
through the sum of the contributions of concrete strength, properties of anchored
material (which is steel for this work), and anchorage depth. In this work, all three
factors and the predictions of current tables and equations related to anchorages are
examined throughout site tests.
