Connection System of Massive Timber Elements Used in Horizontal Slabs of Hybrid Tall Buildings
Publication: Journal of Structural Engineering
Volume 137, Issue 11
Abstract
This paper discusses connections between Cross-Laminated-Timber (CLT) floor slabs and steel framework of hybrid tall buildings. Using the example of a 24-story building analysis, it is shown that such connections can be made using simple fasteners like large screws to enforce efficient diaphragm action in the critical case of CLT slabs subjected to lateral seismic or wind events. Results of laboratory tests on connections between CLT slabs and structural steel members are presented to prove this.
