Widely used simplified analytical methods are not suitable for estimating the tensile force in tie-rods with significant discontinuities or irregularities. To address this challenge, a robust hybrid methodology using a data-driven approach and finite element method is proposed for historical tie-rods. This methodology has been applied to a real case study involving two historical ties.
Widely used simplified analytical methods for estimating the tensile force in tie-rods are clearly not applicable when they contain significant discontinuities or irregularities. A common example for which this fact becomes relevant in practice is the use of connectors to unify historical ties consisting of several segments. To address this challenge, a robust hybrid methodology is proposed which can be applied to any historical tie by employing a data-driven approach to a dataset generated using the finite element method. The methodology is applied to a real case study involving two historical ties.
