This article aims to investigate the load behavior on the tie rods of anchored curtain walls built to eliminate geological-geotechnical hazards on hillsides in the city of Rio de Janeiro. Taking into account increases in overload due to the growth in construction uphill of these structures and the end of their service lives, a simulation was conducted using the Plaxis computational system to estimate the loads on the tie rods of 20 anchored curtains after 50 years. Those results were compared with results obtained from residual load verification tests. The comparison shows that although the theoretical simulations indicate increases in loads over 50 years due to the additional overloads, the tie rods tend to lose load, even with increased overloads in the anchored curtains.
