TUM bond database with full-scale beam tests on anchorages and laps in tension

Abstract

Reliable experimental data is essential for the development and validation of structural design models. However, existing bond databases often lack consistency, traceability, and overall data quality. To address this, the Technical University of Munich (TUM) developed the TUM Bond Database (TUMBD), a curated collection of experimental test data focusing on lap splices and anchorages under tensile loading. TUMBD includes a variety of full-scale beam tests from the primary literature and tests conducted at TUM. The TUMBD currently comprises 1033 lap splice and 189 anchorage tests, with detailed information on geometry, test setup, materials, and experimental results. This paper discusses the database's origin and development, its structure and content, and presents a statistical analysis of the distribution of key parameters. The open-access database supports model calibration and data-driven research, including the use of artificial intelligence and advanced computational methods. Given the complexity of bond behavior, the emergence of new resource-efficient materials, and the potential of such advanced statistical techniques, TUMBD enhances the reliability, sustainability, and efficiency of reinforced concrete construction. Ongoing updates and strict criteria ensure data quality.
