It is shown that exact theory always is needed to give a precise description of fracture behavior for a real calculable reliability in all circumstances. It further is shown that applied cohesive zone models, J-integral, and finite element solutions, are questionable and always need to be explained and controlled by theory. Important is, that these empirical fitting procedures are not able to fit to any relation, as follows from exclusion by the “lack of fit” test. Contrarily, limit analysis theory shows a precise fit (with a coefficient of variation of 10%) to the theory equation and delivers a conclusive confirmation of criticized design rules of Eurocode 5.","wood; limit analysis; fracture mechanics; cohesive zone model; J-integral; finite element method; splitting of timber pin-dowel connections; OA-Fund TU Delft","en","journal article","IJCER","","","","","","","","Civil Engineering and Geosciences","Structural Engineering","","","",""

These rules are lacking but are necessary to be able to provide real and calculable reliability as is required according to European pacts and laws. Necessary therefore are the obtained exact combined bi-axial bending, compression and shear strength equations with the exact equilibrium equations under biaxial loading. As for other materials the elastic-full plastic limit design approach is applied, which is already known to precisely explain and predict uniaxial bending strength behavior. The strength derivation is based on choosing the location of the neutral line. This provides the stress distribution in the beam cross section in the ultimate state for that case, providing the possibility to calculate the associated ultimate bending moments in both main directions combined with the ultimate normal- and shear forces. The derived general strength and equilibrium equations are simplified to possible elementary design equations, applicable for building regulation.","timber beams; limit analysis; stability design; bi-axial bending strength; OA-Fund TU Delft","en","journal article","Bentham Open","","","","","","","","Civil Engineering and Geosciences","Structural Engineering","","","",""
