From an environmental sustainability point of view, modern construction practices increasingly favorcarbon neutral buildings including those made from timber. Prefabricated timber modules havebecome popular due to their efficient in-house production followed by systematic and rapid on-siteinstallation. Construction companies often use these lightweight modules for residential buildings upto six story when feasible. While several studies are available that simulate stiffness and strength ofshear walls, a major component of the module responsible for transferring shear load and acting asa load bearing wall for vertical loads, e.g [1] and [2] for the EC5 design principles, relatively little workhas been done to analyze the structural performance of entire modules. This is likely due to limitedtime span the construction type has been common practice, practical challenges associated withexperimental tests and numerically demanding simulations of large structures. However, there aresome exceptions, e.g [3].This study introduces the concept of “super elements”, which are developed by condensing theinternal degrees of freedom (DOF:s) of a whole timber module to specified parts of its boundary. Theaim of this study is to reduce the number of DOF:s by using substructuring so that an entire structurecan be analyzed while subjected to external loading. Substructuring is a method of dividing a wholemodel into user defined parts (super elements) and coupling these together to create a global model[4]. The internal DOF:s of the super elements are “condensed” using static condensation, and thesuper elements are then connected to the rest of the model along selected restrained DOF:s [5].Figure 1(a) shows an example of a building with timber modules, while Figure 1(b) illustrates partsof a full-size timber module. Figure 1(c) represents a super element of the module. A simple, linearFE super element is developed for analyzing a part of a whole timber structure and it is coupled tothe rest of the structure only at designated pre-selected nodes. The model is then used to analyzethe response during various load cases applied to the whole structure.
