Structural connections for massive timber plate elements in hybrid structures

Abstract

<p>Discussion is focused on connections between massive Cross-Laminated-Timber (XLam) floor slabs and steel skeletons of hybrid structures. Using the example of a 24-storey building, it is shown that such connections can be made using simple fasteners like large screws to enforce composite action in the critical case of XLam slabs acting as diaphragms during lateral seismic or wind events. Results of laboratory tests on connections between XLam slabs and structural steel are presented. It is concluded that hybrid steel-XLam structures can be superior to hybrid steel-RC structures.</p>
