Timber frames are commonly adopted as a structural element in many countries with specificcharacteristics varying locally, in termsof geometry and materials.Their diffusion in Southern European countriesis linked to their good seismic-resistant capacity, but only in the last decade interest has grown for this structuraltypology, and studies have been performed to better understand their behaviour. In this contribution, a briefstate of the art on existing timber frame building typologies is presented, focusing on their seismic-resistantcharacteristics. Additionally, an overview of possible strengthening solutions, adopted both in practice, andtested experimentally are presented. Their performance when applied to walls and connections is also discussed.
