Abstract
In order to establish a rational design procedure for the anchoring depth of the steel posts for rockfall-protection fences embedded into the rockfall-protection walls, static and drop-weight impact loading tests on prototype through-type posts in case of coupling between bending and shear actions were conducted. The results obtained from this study were as follows: 1) plastic hinge was formed in the post near the upper surface of the wall not only under static loading but also under impact loading; 2) impact force excluding high-frequency components may be able to estimate approximately by using the static perfect-plastic load; 3) impact energy may be entirely absorbed by the post deforming excluding rotation of the wall; and 4) design values obtained from the specification may be in the safety side comparing with the experimental results.
