Introduction Historical steel structures constitute a critical component of our architectural heritage, reflecting significant technological and architectural advancements. These structures, encompassing everything from railway bridges to landmark buildings, serve as historical markers and remain functional within modern infrastructure frameworks. However, their longevity is threatened by corrosion, a pervasive issue that undermines structural integrity and safety, thereby complicating preservation efforts (Gocál & Odrobiňák, 2020; Zhao et al., 2023) . Corrosion, a process exacerbated by environmental conditions, necessitates ongoing maintenance to ensure structural safety, presenting significant challenges due to the need for non-invasive techniques that preserve the structural and historical integrity (Di Sarno et al., 2021; Li et al., 2022).

Overcoming the accessibility and limitations of traditional methods, the proposed system employs clamp-based connections, allowing for removable anchoring without invasive interventions like welding or drilling. We demonstrate the applicability and efficacy of this system through Finite Element Model (FEM) simulations and laboratory experiments, validating its load-bearing capacity necessary for maintenance and inspection. Installing these elements on riveted steel bridges highlights the practical application of the developed technology, underscoring its potential for the sustainable maintenance of historic steel structures without compromising their integrity or historical value. © 2024 The Authors.
