Experimentelle Untersuchungen zum Tragverhalten von Holz-Beton-Verbunddecken aus Buche

Experimental analysis on the structural behavior of timber-concrete composite slabs made of beech

At the Institute of Structural Engineering of the ETH Zurich, an innovative timber-concrete composite slab made of hardwood has been developed. This composite slab is made of a 40 mm thick beech laminated veneer lumber plate (BauBuche) and a 120-160 mm thick concrete layer. The beech plates act as formwork and tensile reinforcement. The connection between the two materials is accomplished with 15 mm deep notches in the timber plate, which ensure a stiff composite action. This paper presents the basic concept of the composite slab as well as the extensive performed experimental investigations. This innovative slab system was implemented for the first time in the ETH House of Natural Resources (www.honr.ethz.ch).
