Abstract

Invention of cross-laminated timber (CLT) was a big milestone for building with wood. Due to
novelty of CLT and timber’s complex mechanical behavior, the existing design codes cover only
rectangular CLT panels, simply supported along 2 parallel or all 4 edges, making numerical methods
necessary in other cases. This paper presents a practical engineering tool for stress and deflection
prediction of CLT panels with non-classical boundary conditions, based on the software for the
computational analysis of laminar composites, previously developed by the authors. Diagrams
applicable in engineering practice are developed for some common cases. The presented
methodology could be a basis for more detailed design handbooks and guidelines for various layouts
of CLT panels and different types of loadings.
