“…The analyses of timber joint mechanics range across analytical, numerical, and experimental methods. Some focus on validation between experimental and numerical methods (Lang and Fodor, 2007;Guan et al, 2008), while others use a variety of analytical models that are compared against physical tests (Schmidt and Mackay, 1997;Shanks and Walker, 2009;Shope, 2016;Fang and Mueller, 2018).…”

“…Structural analysis of each is necessary, and creation of models with structural analysis software makes this possible during the design stage. Research efforts to model traditional TF structural performance have primarily focused on the behavior of mortise-andtenon joints (Erikson and Schmidt 2003;Shanks and Walker 2009;Bulleit et al 1999). Structural modeling of whole-system TFs, however, has not been performed and presented in the literature as for LFs.…”

Gravity and Wind Load Path Analysis of a Light-Frame and a Traditional Timber Frame Building

The objective of this study was to compare structural load path and system behavior of a light-frame (LF) and a timber frame (TF) structure. This load path analysis is part of a broader research effort that compares LF to TF residential structures. Structural analysis software was used to create a model of each structure. The TF structure was composed of large-dimension timbers and structural insulated panels (SIPs). An equivalent LF structure was designed for comparison, following the guidelines of the International Residential Code. Results show that TF outperforms LF in resisting uplift, as well as in story drift. TF also provides load paths that are more resistant to the introduction of large openings and the loss of a central post. Observed axial loads in TF posts show smaller ranges compared with LF studs.

“…The bearing capacity of mortise and tenon joints is a function of the angle of the connection, and length of the toe and mortise depth [1,14,17]. The lack of knowledge about this particular joint is determinant in the assessment of the load carrying capacity of existing wooden structures [9,31,4,5]. Here, the objective are to quantify the strength capacity of the joint by physical testing of full-scale specimens, to validate the possible usage of semi and non-destructive testing techniques to predict the joint properties and the joint effectiveness and to validate the adequacy of an anisotropic failure criterion to represent the behaviour of the joint by the comparison between experimental and numerical results.…”

Testing and modeling of a traditional timber mortise and tenon joint

The structural safety and behaviour of traditional timber structures depends significantly on the performance of their connections. The behaviour of a traditional mortise and tenon timber joint is addressed using physical testing of full-scale specimens. New chestnut wood and old chestnut wood obtained from structural elements belonging to ancient buildings is used. In addition, the performance of different semi and non-destructive techniques for assessing global strength is also evaluated. For this purpose, ultrasonic testing, micro-drilling and surface penetration are considered, and the possibility of their application is discussed based on the application of simple linear regression models. Finally, nonlinear finite element analysis is used to better understand the behaviour observed in the full-scale experiments, in terms of failure mode and ultimate load. The results show that the ultrasonic pulse velocity through the joint provides a reasonable estimate for the effectiveness of the assembly between the rafter and brace and novel linear regressions are proposed. The failure mechanism and load-displacement diagrams observed in the experiments are well captured by the proposed non-linear finite element analysis, and the parameters that affect mostly the ultimate load of the timber joint are the compressive strength of wood perpendicular to the grain and the normal stiffness of the interface elements representing the contact between rafter and brace.
