Hybrid Wall-Slabs for Multi-storey Buildings: Made of Timber with a Directly Applied Mineral Cover Layer

摘要

A sustainable handling of the worldwide available resources requires an innovative and comprehensive ecological concept especially for multi-storied timber buildings. Therefore, profound investigations were done with the aim to develop an efficient composite system, which combines the distinguished properties of wood with common mineral building material anhydrite. This mineral has a high capacity to accumulate thermal energy and moisture for a balanced indoor climate. Anhydrite layered walls, made of stacks of boards or solid crosswise nailed timber, are developed and investigated for modern residential multi storey buildings. The mineral layers are in direct connection with the timber. The serviceability under vertical and horizontal load was examined. Numerical structural models were developed and verified with the results of measurement by Close-Range Photogrammetry (CRP) experimental tests.
