Abstract:
Experimental tests with post-installed anchors in cracked concrete were performed to investigate anchor failure mechanisms associated with tension cycling at near-ultimate load levels. The test results challenge existing assumptions about the behavior of anchor bolts used to connect structural and nonstructural elements in the event of an earthquake. Specifically, they demonstrate that the current definition of ductility in anchor design guidelines must be improved. The influence of the tension load cycling frequency and cycling pattern on anchor behavior are also discussed.
