Abstract
A new code for the design of the guard fence performances was implemented and issued
in April 1999 in Japan The prescribed performances of the new code are: i) prevention
of derail, ii) safety of occupant, iii) leading vehicles to road, and iv) prevention of
spreading out the broken pieces. In the new code, the full-scale experiment for checking
the performances of guard fences is required in the determination of the structure of the
guard fence. However, it is very difficult to test the performance of full-scale guard
fences in the field for the parametric examination because of the huge time and cost
consumption. In this study, the numerical analysis using LS-DYNA under the simulated
condition of the t
