Experimental Verification of Ceiling Joint Performance in CLT-Steel Hybrid Structures

Abstract

In the research for sustainable hybrid structures, cross-laminated timber (CLT)-steel structures have gained widespread popularity and become a widely used engineered solution. This paper points out the unused potential of CLT-steel hybrid ceiling systems, focusing on creating the effect of a continuous deck. The study aims to create a connection capable of interconnecting panels through a hidden beam. The essence is to prevent the decks from rotating at the point of support, thus reducing overall slab deflection. Following the initial adjustment of the proportions of the connection, it is possible to state that the assumptions have been met. The results from the numerical analyses present two variants of the connection, which can be further subjected to experimental analyses.
