Abstract

A numerical strategy is developed to investigate the dynamic behaviour of falling rock protection barriers, metallic structures widely used as passive measures against rock fall. The modelling procedure is validated on a series of full scale impact tests carried out onto different barrier prototypes. Three numerical models were developed and analyses were carried out at various levels of impact kinetic energy. The paper presents some essential details of the numerical strategy as well as the main results, discussed with special emphasis to their relevance towards design.
