Abstract

A simply supported and continuous cross-laminated timber (CLT) floors with uniformly distributed loads and point loads were analysed using the Vierendeel Method (VM), in which each layer of the CLT is represented by an individual beam element and the connections between layers are idealised into vertical connecting beam elements. The VM models were created using different end release conditions and element formulations. Comparing the resulting deflections, flexural and shear stresses with those determined using the Gamma Method, Shear Analogy Method and a 2D FEM model, it was found that the VM models with rigid connections between the CLT layers and the Timoshenko beam formulation performed most similarly to Gamma Method and Shear Analogy Method for predicting axial and shear stresses, but tended to over-predict the deflections. Recommendations for future research are made for extending this method such that it can be used for analysing timber-concrete-composite floors that use CLT as the timber component.
