Prediction of torsional stress at in-plane shear loading of cross laminated timber

The main aim of this paper is to investigate in- plane shear behaviour of CLT composed of seven layers (CLT 7s). The focus is here on models for prediction of the torsional stress acting in the crossing areas between laminations of adjacent layers. Predictions according to proposed design models are compared to results of finite element (FE) analysis. The study presented concerns the influence of the element lay-up in terms of the thickness of the longitudinal and transversal layers, respectively. In a wider perspective, the aim of this paper is to contribute to the development of consistent design approaches for CLT at pure in-plane shear loading and in-plane beam loading conditions, giving similar but not identical internal force distributions.
