Considering wood currently used in construction domain, it may be observed that it possesses good strengths, but reduced modules of elasticity. This drawback may be prevented by creating structures with rigid nodes or by using hybrid or built-up cross-sections for the structural elements. The paper consists of numerical analysis of a timber frame with rigid nodes, assuming built-up cross-sections for the structural elements, made of four chords with cross-sectional dimensions of 0.1x0.1 m each - for columns and two chords of 0.1x0.1 m each - for beams. Analyzing this type of structures by considering equivalent cross sections' properties of the structural elements, the real phenomena may not be covered, since it doesn't consider all elastic characteristics of wood, resulting in different stress' distribution in the structural elements. The analysis of this structure considering both real solid cross-sections and all elastic properties of wood by using specialized software, leads to a laborious work because of the high number of finite elements. Thereby, a two-step analysis is proposed: the first one consists in solving the spatial timber frame with bar type finite elements and the elastic properties parallel to the grain, as provided by design codes. In the second step, an intermediary node is detached and loaded with the internal forces obtained from the first step, considering all elastic parameters of wood and using solid type finite elements. Currently, in the design process, only the first step in performed. The two-step analysis aims to compare the results with those obtained using the strength of materials methods, relieving the necessary corrections in the case of one-step design process.
