This paper presents the results of investigation into the capacity of a deformable support system (D-Bolt) to handle various types of dynamic events. Instrumented D-Bolts and plates were subjected to drop tests, providing insights into the effects of dynamic loading onto dynamically resistant bolting systems.
Strain measurements are taken during and after the impacts on the bolt. A correlation is drawn from the static performance of the components and their dynamic resilience. A discussion on the reaction of a support system to various forms of dynamic events is presented and suggestions on further requirements of dynamic support system are put forward. Comparison to design methods and support system calculation are offered. Suggestions on dynamic testing protocols are also offered.
