Type: book-chapter
Abstract: Extending Danish proof load testing practice from single‑span tomulti‑span concrete bridges introduces additional challenges related tonegative‑moment behavior, load redistribution, and uncertainties inboundary conditions. Recent Danish research highlights the importance ofrealistic load application and robust monitoring to ensure safe testing,principles that also apply to continuous structures. This paper presents keyconsiderations for developing a controlled and safe proof loading approach formulti‑span slab bridges based on the Danish classification‑vehicleloading and reliability‑based target loads. A three‑spancontinuous concrete slab bridge is used as a representative case to illustrateload placement strategies, feasibility constraints, and monitoring requirements.Simulated laboratory investigations on non‑shear‑reinforced slabswith continuous supports provide insight into early flexural cracking andshear‑critical behavior, forming a basis for defining stop criteria. Thecombined findings are deemed to support the development of a structured proofloading procedure for multi‑span bridges, enabling controlled proof loadtesting.
