Condition assessment of existing bridges: Serviceability limit state (SLS) loading and non‐destructive test (NDT) methods : Testbed and demolition of the Kalix Bridge
This document is the final report for project BBT 2020‐013 (Trafikverket). It presents the results for the development and testing of a loading system based on realistic convoy loads for serviceability limit state (SLS) applied to the Kalix Bridge. It also includes a determination of the bridge condition through non‐destructive testing (NDT) and assessment of non‐destructive methods for the determination of residual prestressing forces. The work carried out included the development of linear and non‐linear finite element models and their calibration based on the information collected in the experimental part. Digital twin models intended for the prediction of bridge response were also performed, and novel AI‐based methods for crack detection were evaluated. In addition, a framework for condition management based on reliability and robustness measures was developed within the scope of the project. As the Kalix Bridge was replaced by a new structure in 2022, the report summarizes a comprehensive review of methods for demolition of prestressed bridges and presents a methodology for demolition based on numerical analysis of the structure, considering the specific characteristics of the project and existing information about the bridge. ; Författare: Gabriel Sas, Jaime Gonzalez‐Libreros, Cosmin Daescu, Chao Wang, Lennart Elfgren, Angelica Chavez, Silvia Sarmiento, Ali Mirzazade, Vanessa Saback, Adrian Ulfberg, Dongyun Liu, Jie Cao, Raid Karoumi, Gabriel del Pozo, Mario Plos, Kamyab Zandi, Sebastian Thöns, Ivar Björnsson, Cosmin Popescu, Björn Täljsten, Bård Arntsen, Mats Holmqvist, Syed Abrar, Imran Tamboli, Sanat Wable, Werner Bjerke, and Kamal Raj Chapagain ; Tillståndsbedömning av befintliga broar – Bruksgränstillståndsbelastning och icke-förstörande provningsmetoder
