| Abstract: |
The complex behaviour of anisotropic wood material and semi-rigid connections in knee joints of timber portal frames leads to a discussion on additional design conditions entailing strength failure criteria. Also the assessment of the consequences of deformation development and increase of global displacements of a system due to the load duration impact in semi-rigid connections is essentially important for a sustainable design. Some important affecting factors: the resistance of wood in tension perpendicular to the direction of the grain, development of deformations in semi- rigid connections and uncertainty of bearing capacity are examined regarding their role in a safety format. |
