Structural building systems using cross-laminated timber (CLT) are steadily gaining popularity due to their huge advantages over traditional technical solutions. The lightness of the material, the pliability of the mechanical joints of the panels provides a potential high seismic resistance of buildings made of CLT, despite irreversible damage to the wood panels in the joints. As a result of the inherent competitiveness of cross-laminated wood, their use is gradually increasing worldwide. The article presents a brief review and analysis of existing domestic and foreign regulatory and technical documents and the results of studies performed in the field of calculation and design of buildings based on CLT panels erected in earthquake-prone areas. The results of experimental studies aimed at studying the features of the operation of CLT panels with different numbers and arrangement of lamella layers under the influence of static and dynamic loads simulating seismic effects are presented. The results of recent achievements in the field of experimental studies of CLT building structures under seismic loads are reviewed and summarized to demonstrate current progress, problems and future directions of research.
