Bending Stiffness of CLT-Concrete Composite Members - Comparison of Simplified Calculation Methods

Cross-laminated timber (CLT) is currently a highly efficient material for the bearing structures of timber buildings. The combination with concrete in composite cross-section disposes of many advantages. The paper analyses some of the available analytical calculation procedures for determining the bending resistance of these multilayer laminated panels. The aim is to assess their suitability for the determination of the resistance of composite CLT-concrete beams, where concrete and wooden layers are connected rigidly by adhesive.
