Behaviour of anchored structures at failure – physical testing and numerical modelling
Behaviour of anchored structures at failure – physical testing and numerical modelling
A large number of geotechnical procedures and methods are based on achieving a sufficient level of safety during the design phase. However, such approaches can only be used to a limited extent for existing structures, as a decrease in safety can generally be assumed. Therefore, damage and its effects must be modelled, and often only limited knowledge of the structure and the underground is available. This topic was analysed with reference to anchored structures, which often suffer considerable damage due to corrosion of the tendons or are affected by changes in earth and water pressure. Due to the lack of suitable modelling approaches and material laws, an experimental representation of a damaged anchored structure was carried out, accompanied by a series of numerical investigations. In this way, an attempt was made to determine the redistribution capability of both subsoil and structural components. The aim of these investigations was to identify methods and approaches for considering damage in the analysis of anchored structures. It became evident that an accurate depiction is only possible to a limited extent, requiring a number of assumptions. Based on this, a simple and practical method was subsequently derived to enable an assessment of damaged anchored structures.
