Abstract

This study examines the racking strength and stiffness of CLT panels manufactured from C16-grade timber using Irish Sitka spruce. The timber obtained from Sitka spruce in Ireland is typically graded as C16. In Europe, CLT is primarily manufactured with C24-grade timber, and most of the research available on the structural behaviour of CLT is presented for C24-grade material only. In this study, C16 grade material is examined by subjecting full-scale CLT panels manufactured using C16-grade CLT to racking resistance tests. The CLT wall panels are connected to CLT floor panels using only angle brackets and screws. A preliminary investigation has been conducted to verify the feasibility of a non-standard application of angle bracket connectors for the design of a multi-storey modular building using CLT made from C16-grade Irish timber.
