SOTOMAYOR-CASTELLANOS, Javier Ramón. Static bending behavior of old Picea abies wood beams. Nova scientia [online]. 2015, vol.7, n.13, pp.208-227. ISSN 2007-0705.

The architectural typologies found in the context of the structural analysis of constructions with historical and cultural meaning, are complex. Numeric modeling is proposed as a solution to diagnose the structural safety of the edifices. In this research, acoording to European standard EN 408, static bending tests were performed and the moduli of elasticity and of rupture corresponding to five old beams of Picea abies wood were calculated. The wood density was of 422 kg/m³ for beams with a moisture content of 12 %. The average modulus of elasticity was of 9,059 MPa and the modulus of rupture was 29.176 MPa. The moduli of elasticity and of rupture of the beams presented an acceptable variability. The experimental results were contrasted with the numeric predictions employed by the finite element method. The numeric prediction in the linear and nonlinear domains showed a good approximation with the experimental results.
