WSE Defense: Multi-Scale Dynamic Monitoring and Behavior of Cross-Laminated Timber Elements and Systems

Cross-Laminated Timber (CLT) is one of the latest engineered wood products to show promising structural features for a variety of structural purposes. For CLT to be widely adopted, its dynamic behavior needs to be fully evaluated through experimental and numerical methods. Therefore, it is important to the continued expansion of CLT use, to further understand the influence of environmental hazards and factors such as earthquakes and moisture exposure. This dissertation sets out to contribute to the understanding of CLT’s dynamic parameters using a multi-scale approach. The focus of the dynamic identification of CLT in this dissertation centers on three scales, namely: (1) the building scale, (2) the structural system scale, and (3) the structural element scale. The building scale’s dynamic identification and finite element results help illustrate the impact of non-structural components to the dynamic behavior of a CLT building under service conditions. Results on the system scale experiment illustrate effects of applied ground motions and structural retrofitting based on observed damage. Tests conducted on the CLT element scale illustrate that the floor element stiffness was not affected by weathering cycles. Based on the findings of this study, areas of future work on the dynamic identification of CLT structures were identified.

Ignace Mugabo was born in the Democratic Republic of Congo and grew up in Rwanda. He did his undergraduate studies in Civil and Construction Engineering at the University of Arkansas at Little Rock. He is currently pursuing a dual Ph.D. in Wood Science and Civil Engineering. While at Oregon State University, he worked on research involving the dynamic identification of CLT. After graduation, he plans work for KPFF Consulting Engineers in Portland, OR.
