Abstract

An extensive experimental programme aimed to develop multi-storey timber buildings for non-residential applications has been undertaken at the University of Canterbury, New Zealand. A performance requirement, among others, is that the floors must be medium to long-span, so as to allow open spaces. In addition, a prefabricated solution is preferred in order to take advantage of the prefabrication process, as commonly done in precast reinforced concrete and steel consruction. Due to those requirements, a semi-prefabricated timberconcrete composite system has been developed. This paper reports the results of the tests to failure performed on 11 full-scale beam specimens representative of semi-prefabricated timber-concrete composite floor strips. Four connection types (metal plates pressed onto the LVL beams, triangular notches, large and small rectangular notches cut from the LVL beams) were selected based on the outcomes of previous research. The experimental tests demonstrated that a small number of inexpensive connectors are able to provide a stiff connection system. The high degree of composite action achieved makes the proposed system suitable for medium to long-span floors.
