A new methodology to assess the structural safety of anchored retaining walls

This paper proposes an assessment technique for the structural safety of anchored concrete panels after anchor ruptures. The methodology was developed using anchored panels located in Gramado-RS, Brazil, where 41 anchors ruptured at different positions. Being the original project of the panels known, their structural safety was evaluated using a finite-element software. Bending moments and punching were verified for each panel and their structural safety was classified into stability levels. The results were compared to in situ observations from technical inspections. The calculation methodology proposed in this research showed to be a useful tool for analyzing the structural stability of anchored panels.
