Abstract

It is reported on first results regrading a novel column-to-slab connection suited for multi-storey timberbuildings. The emphasis is on the development of a new constructive solution for a scalable, bespoken connection type,which enables to overcome today’s rigid rectangular floor grid restrictions, thus enabling open-plan and flexible spacearchitecture. The paper firstly reveals some of the recent developments of column-to-slab solutions in engineered timberconstruction. Then the constructive detailing, the finite element based modelling and some test results of a bondedconnection, manufactured exclusively out of wood, are presented. The novel solution is based on specific orthogonallylayered and stepped inserts, based on laminated veneer lumber (LVL) from beech wood, which are bonded into preciselyfitting cavities in the CLT. The connection was developed within the frame of the Science Cluster of Excellence IntCDC(Integrated Computational Design and Construction for Architecture), allocated at the University of Stuttgart.
