Abstract

The deformation behaviors of guardrails under both static and impact transverse loads and their contributions to the energy absorption are studied experimentally in this paper. Scaling-down tests are conducted and the specimens are about one-third of the real engineering guardrails in geometry. In order to measure the contribution of each kind of deformation to the energy absorption with the variation of transverse loads, single loading and multiple loading-unloading procedures are used in the static experiments. The impact tests are carried out in a drop-hammer system, and the effects of different boundary conditions on the energy absorption and peak load are investigated.
