  • Description:
    This U.S. Bureau of Mines report presents the results of verification tests conducted on arch canopies constructed of liner plate. Verification tests were conducted to demonstrate the use of the static and dynamic test procedures developed for arch canopies and to establish the validity and conservativeness of the arch canopy design procedure developed by the Bureau. Physical dynamic tests served as the basis for evaluating the design procedure. Actual dynamic response of the arch canopies was compared with their predicted response utilizing the design procedure. The dynamic tests demonstrated that the actual energy absorption capacity of the arch canopies exceeded the predicted capacity from 18.2 to 30.9 pct, for an average conservative error of 23.5 pct. These tests showed that the arch canpies possess more energy absorption capacity than the design procedure allocates and that the design procedure yields conservative designs. The results of the dynamic tests were also used to develop an empirical factor, which relates the energy of impacting loads to the energy absorption capacity of arch canopies. Use of this empirical factor improved the design procedure by decreasing the average conservative error in predicting the energy absorption capacity of arch canopies to 4.6 pct.
