P. Nechanický & P. Kuklík Department of Steel and Timber Structures, Czech Technical University in Prague, The Czech Republic ABSTRACT: Timber-concrete composite structures are coming to be very important in housing sector. They have many advantages compared to traditional timber floors and are widely used as an effective method for refurbishment of existing timber floors. Current research at CTU is focused on industrial production of prefabricated timber-concrete panels and their easy and quick assembly, in order to reduce the total cost of production, transport and assembly. A new shear connector was developed for those purposes. It is a punched metal plate fastener with double-sided teeth and omitted area nearby contact of timber and concrete. Direct shear tests were performed on four series of punched metal plate fasteners with different geometrical properties. Results of these tests and determination of slip modules Kser and Ku is presented in this paper. 1 INTRODUCTION Timber-concrete composite structures are becoming very important in the housing sector. They have many advantages compared to traditional timber floors and are widely used as an effective method for refurbishment of existing timber floors. Due to the many benefits they are now being used more in new multi-story timber framed houses.
