摘要：The design of wood frames with continuity in nodes and hybrid portions (timber composite strips) is complex as a result of the use of two materials, of the structural composition and of the iterations which are necessary for the defining the solutions. Partial hybridisation (hybrid areas) of the wood beams is made with thin strips (max 4 mm thickness) due to economic conditions. The composite strips are made of identical lamellas like unidirectional matrix – type lamella. In the unidirectional fabric, for obtaining a maximum effect, the fabric threads are parallel to the wood fibres from the hybrid beam. The paper presents the engineering algorithm of these structures and comprises the following stages: fixed form, pre-dimensioning of the composite strips, the equivalent form, iterations of the equivalent form.
