Analysis and Strengthening of Timber Floors and Roofs

In many countries, traditional construction comprises floors and roofs systems in wood. Current knowledge assumes the need to preserve and to protect existing wood systems with important advantages to the overall behaviour of the building. In this paper, after a description of the most common systems used in traditional wooden floors and roofs, strengthening techniques are presented. For that, the analysis and design of the existing structures is discussed and the effectiveness of the strengthening techniques is evaluated through experimental results obtained in laboratory.
