Flexible rockfall barriers are a common form of protection against falling blocks of rock and
rock fragments (rockfall). These barriers consist of a system of cables, posts, and a mesh …

The so-called “bullet effect” refers to the perforation of a rockfall protection mesh by impact of
a small block, which has a kinetic energy lower than the design value, where the design …

Rock fall barriers are usually designed considering the possible range of boulder energy
upon impact. Different combinations of mass and speed can result in the same impacting …

This paper investigates the dynamic response of low energy, semi-rigid rockfall barriers. The
study is based on a FE model that reproduces the geometry, components and connections …

Most of the recent research on rockfall and the development of protective systems, such as
flexible rockfall barriers, have been focused on medium to high levels of impacting energy …

In rockfall science, the bullet effect refers to the perforation of a rockfall mesh by a small
block traveling at high speed. To date, there is still no comprehensive experimental data set …

The imperative need to protect structures in mountainous areas against rockfall has led to
the development of various protection methods. This study introduces a new type of rockfall …

Full-scale impact tests, carried out to evaluate the behaviour of flexible falling rock protection
barriers, are described and relevant results presented and discussed. Falling rock protection …

Flexible catch fences are widely used to protect infrastructure like railways, roads and
buildings from rockfall damage. The wire meshes are the most critical components for catch …

Rigid barriers can be destroyed by the impact of rock boulders in rockfalls, landslides and
debris flows. An estimation for the maximum magnitude of the impact force is significant for …
