The design of tall timber buildings (TTBs) is often governed by wind-induced vibrations at the serviceability limit state (SLS) due to the low density and stiffness which make these structures more flexible and susceptible to wind effects. Controlling sway-induced deformations and accelerations is critical to ensure occupant comfort and structural performance. This chapter provides an overview of the key dynamic properties, such as natural frequency and damping ratio, that significantly influence wind response, then explores the role of lateral load-resisting systems (LLRS) in mitigating the deformations and vibrations in TTBs under wind loads. Additionally, advanced methods for evaluating wind-induced responses, such as computational simulations and experimental wind tunnel testing, are discussed. Performance-based wind design (PBWD) is presented as a promising approach to address the limitations of traditional codes. The study highlights the importance of accurately predicting deformations and dynamic parameters while optimizing structural systems to meet SLS criteria and ensure safety and comfort.
