Numerical studies on the influence of selected construction features and road conditions on the performance of road cable barriers

Abstract

Cable barriers are commonly used on Polish roads, including motorways and local roads. Their main elements are pre-stressed wire ropes, which are usually anchored at two ends in concrete blocks buried in the soil. In this work numerical studies concerning the influence of selected construction features and parameters of the vehicle motion on the performance of cable barriers were performed. Numerical simulations are a useful tool to conduct such analyses that is now being used more and more. The calculations were carried out by using finite element code of LS-DYNA.
