Flexible retaining structures supported by anchor beams: The problem of tie-rod length

Research output: Chapter in Book/Report/Conference proceedingConference contribution

Abstract

The stability of single-anchored flexible retaining structures strongly depends on the anchor force which needs to be applied to the wall and supported by the anchor beam. One important issue in the stability is tie-rod length. Tie-rod length is often defined using simple mechanical and geometric considerations or using classical global stability methods such as Kranz's method. However, the simplicity of those considerations and the imposed mechanisms in methods such as Kranz's may lead to inaccurate results. In the present paper, a finite element implementation of the upper-bound theorem (Sublim3D) is used in determining the minimum length needed to ensure stability for different geometries of the wall and of the anchor beam. The obtained mechanisms and tie-rod lengths are analysed and compared with those from classical methods.
