This study aims to clarify fundamental concepts related to the design of Cross-Laminated Timber (CLT) multi-storey buildings in seismic-prone areas. An in-depth worked example of a CLT multi-storey building design is presented following four different cases of analysis: low and medium ductility according to the current Italian regulations (NTC 2018), and medium and high ductility (DC2 and DC3) according to the new draft of Eurocode 8. Finite Element (FE) models of the building have been implemented to analyse the linear dynamic behaviour of the structure. In high ductility class, a couple-panel behaviour of shear walls is achieved by following the analytical provisions reported in the new draft of the Eurocode 8. As a result, a clear design process is defined for each case analysed. Through the analysis of the individual steps, possible issues in the interpretation and application of the rules are highlighted and resolved. Finally, this study allows an easy and direct comparison between the various cases.

Abstract

This study aims to clarify fundamental concepts related to the design of Cross-Laminated Timber (CLT) multi-storey buildings in seismic-prone areas. An in-depth worked example of a CLT multi-storey building design is presented following four different cases of analysis: low and medium ductility according to the current Italian regulations (NTC 2018), and medium and high ductility (DC2 and DC3) according to the new draft of Eurocode 8. Finite Element (FE) models of the building have been implemented to analyse the linear dynamic behaviour of the structure. In high ductility class, a couple-panel behaviour of shear walls is achieved by following the analytical provisions reported in the new draft of the Eurocode 8. As a result, a clear design process is defined for each case analysed. Through the analysis of the individual steps, possible issues in the interpretation and application of the rules are highlighted and resolved. Finally, this study allows an easy and direct comparison between the various cases.
