Thermische Lastansätze für Fertigteil-Sandwichfassaden unter Berücksichtigung moderner Bauweisen: Erkenntnisse aus experimentellen und numerischen Untersuchungen

Thermal load assumptions for precast insulated sandwich panels considering modern construction methods – Insights from experimental and numerical studies. Precast insulated sandwich panels are an essential component of modern precast concrete constructions. From an engineering perspective, these multi-layered components represent highly complex load-bearing systems, with the facing shell often simplistically treated in practice. The increasing use of highly efficient facing panels with thicknesses of up to 20 mm requires an urgent revision of current practices and design guidelines. A precise consideration of thermally-induced climatic influences is crucial for economical and safe structural design. As part of a research project funded by Zukunft Bau of the Federal Ministry for the Environment, Nature Conservation, Building and Nuclear Safety (BMUB) and led by the Chair of Concrete and Masonry Structures at the Technical University of Munich (TUM), comprehensive experimental and numerical investigations into the thermal responses in the cross-sections of the facing shells on sandwich walls have been conducted. The findings inform proposals for cross-section-dependent thermal load assumptions for sandwich panels.
