“…Similarly, the desired level of accuracy required and associated computational time requirements can be managed simultaneously to address most engineering applications. FEM allows entire designs to be constructed, refined, and optimized before the design is built (Castro-Fresno et al 2008). This powerful design tool has significantly improved both the standard of engineering designs and the methodology of the design process in many civil applications.…”

This study addresses the failures in the Church of Baldornon, in Gijón, Province of Asturias, Spain, and proposes a retrofitting procedure based on the design of experiments (DOE), finite element model (FEM) analysis, and experimental tests. The failures are due to lack of soil stiffness, giving rise to an important structural damage. To tackle this problem, a practical solution based on the nonlinear coupled analysis of the soil and a reinforced concrete structure by FEM is proposed. The solution is to strengthen the previous existing rock-filling wall by means of gunite concrete and counterforts with anchorages embedded in the soil. Finally, conclusions and lessons learned from this study are detailed.

“…A general purpose finite element program ANSYS [16], which has proved to be capable of simulating various problems in structural mechanics [17][18][19][20][21][22][23], was used for the three dimensional finite element analysis of the second phase of the study. The numerical modeling details and assumptions were verified against experimental results before conducting parametric studies.…”

“…(Lopez, 2007;Castro-Fresno et al, 2008;Betegon et al, 2006) Moreover, the application of this kind of analysis permits an energy balance to be carried out during the process, allowing us a better understanding of the phenomenon studied. This is because of their nonlinear behaviour with respect to tensile forces.…”

The use of brakes or energy dissipaters in the anchorages of rockfall barriers is based on their great slip resistance capacity. The brake energy dissipaters can dissipate the kinetic energy produced by the impact of rocks, which is transmitted to them through the system made up of a network of wires, poles, guided cables and anchorages. The dissipaters transform kinetic energy into heat through their deformation (strain), thus increasing the dynamic performance of the screens against falling rocks. These dissipating elements consist of two tubular steel loops (bearing ropes, ties) joined by two aluminium compression sleeves at its extremities, which are under pressure depending on the slip resistance that is desired. In this work a comparative analysis of results obtained from two tensile tests is carried out simulating the slip of the brake energy dissipaters when they are working. The first tests were carried out with a static tensile load. These tests were conducted on a bench with a hydraulic jack varying the tightening pressure on the dissipater's compression sleeves. The second test was the nonlinear dynamic simulation of symmetrical tensile tests and fixed point of the brake energy dissipater. This simulation was performed using the explicit finite element method (FEM), varying the coefficients of friction and speed of slippage between the bearing ropes. The numerical results of these studies show the correlation between the dissipation energy in the tensile tests and the fixed point between the two experiments. In addition, some complementary improvements with respect to the location and geometry of the design of these brake energy dissipaters are made by correcting the efficiency of brake energy dissipater and anchorage set of the rockfall barriers.
