Building in urban centers increasingly requires the use of underground space. Faced with this, efficient Reinforced Walls are required to ensure safe excavation of neighboring structures. Several design methods for this structures and softwares are available, most of them commercial and with a complex interface. This study evaluates the potential of the software Ftool, created by Tecgraf / PUC-Rio for analysis of structures, as a preliminary tool for anchored wall’s design. The principal case studied here, is an anchored wall built in the city of Curitiba, state of Paraná, in a region where the soil belongs to the Guabirotuba Formation. This work counted with instrumentation by inclinometers positioned in the most critical region of the structure where bigger horizontal displacements measurements were observed those the predicted in project. At the end of the simulations a horizontal displacement curve was reached which was compared to that obtained by the instrumentation. The expected final displacements were within the range of measured displacements. A discussion is presented at the end regarding the modeling of the wall by Ftool, with respect to the use of the Winkler’s spring element model.
