Abstract

A methodology for modeling multi-layered structures is presented. The formulation is easily utilized in the framework of existing structural analysis programs to compute internal forces and the global and local deformations of multi-layered structural members and systems. The methodology is fully applied and verified for the case of multi-layered timber beams with semi-rigid connections between the layers. The verifications are performed using both static experimentation and detailed computational modeling with linear and nonlinear finite element analyses. Extension to curved members is also included where emphasis is focused on residual stresses due to construction procedures of layered timber arches. Finally, experimental and computational demonstration of the methodology is given from timber ribbed shells where reasonable agreement between model predictions and experiments is illustrated.

Timber framing

Timber framing (Holzfachwerk) and "post-and-beam" construction are traditional methods of building with heavy timbers, creating structures using squared-off and carefully fitted and joined timbers with joints secured by large wooden pegs. If the structural frame of load-bearing timber is left exposed on the exterior of the building it may be referred to as half-timbered, and in many cases the infill between timbers will be used for decorative effect.

Dome

A dome () is an architectural element similar to the hollow upper half of a sphere. There is significant overlap with the term cupola, which may also refer to a dome or a structure on top of a dome. The precise definition of a dome has been a matter of controversy and there are a wide variety of forms and specialized terms to describe them. A dome can rest directly upon a rotunda wall, a drum, or a system of squinches or pendentives used to accommodate the transition in shape from a rectangular or square space to the round or polygonal base of the dome.

Finite strain theory

In continuum mechanics, the finite strain theory—also called large strain theory, or large deformation theory—deals with deformations in which strains and/or rotations are large enough to invalidate assumptions inherent in infinitesimal strain theory. In this case, the undeformed and deformed configurations of the continuum are significantly different, requiring a clear distinction between them. This is commonly the case with elastomers, plastically-deforming materials and other fluids and biological soft tissue.
