Point-supported flat slabs made of cross laminated timber (CLT) for multi-storey buildings pose various challenges to structural timber design. One aspect are concentrated compressive loads, which cause stress concentrations in the form of shear and compression perpendicular to the grain at the point supports. The present work deals with this problem and shows a method, how the support area can be reinforced with a system connector. After a specification of the connector, the functionality of this construction element is described on the basis of experimental, numerical and analytical studies for a symmetrical loading. The interaction of the connector with the (CLT) is presented with an anlaytical model and numerical simulations, and evaluated with mechanical tests.
