Long-Term Performance Of Timber-Concrete Composite Flooring Systems

Timber concrete composites (referred to as TCC beams here onwards) consist of a concrete slab integrally connected to the timber joist by means of a shear connector. The coupling of a concrete layer on the compression side and timber on the tension side of cross-section results in efficient use of both materials. As the timber joist is mainly subjected to tension and bending while the concrete flange is mainly subjected to compression. The connection plays an important role for the composite action in determining the structural and serviceability performance of the system. Use of stiff and strong connection system contributes to a suitable bending strength and stiffness of the TCC together with other mechanical properties. Design of timber…
