Numerical analysis of the performance of wire mesh and cable net rockfall protection systems

The top horizontal rope is an essential element in the design of wire mesh and cable mesh systems. The study also shows that the inclusion of interior horizontal support ropes does not reduce the stress within the mesh, and accordingly, provides no mechanical benefit. Results show that the use of vertical ropes eliminates stress concentration around the anchor support and reduces stresses on the top horizontal rope provided that they are clamped to the mesh at closed intervals.
