Special Issue Information

Dear Colleagues,

Thanks to the sustainable and renewable attributes of wood, timber building has been subject to significant attention around the world and has been rapidly developed in recent years. Existing engineering examples have proven that timber structures have significant application prospects in high-rise and open-span buildings.

To make full use of wood materials and improve the mechanical properties of timber members, it is reliable and efficient to form timber composite structures by introducing other building materials, such as steel, concrete, bamboo, etc. Continuous innovative studies on timber composite structures are necessary in order to improve their structural behavior, long-term performance, fire resistance, as well as their vibration and sound insulation performance.

This Special Issue will showcase high-quality original research articles on the latest developments of timber composite structures with various combinations. The scope of the Special Issue includes (but is not limited to) timber–concrete composite structures, steel–timber composite structures, bamboo–wood composite structures, and the application of composite materials in timber structures. In addition, this Special Issue also provides space for review papers to provide insights into research status and development tendency. We are pleased to invite you to provide your invaluable articles to our Special Issue.

Thermal responses of wood significantly depend on the dehydration and pyrolysis processes. However, the dehydration and pyrolysis of wood are not well understood. In this study, the thermal model of wood, considering the temperature-dependent thermo-physical parameters, was presented. Differential scanning calorimetry (DSC) experiments were conducted on the Douglas fir wood with different moisture contents to validate the apparent specific heat capacity submodel. Subsequently, the thermal model was, respectively, implemented in the finite element software Abaqus 6.14 and finite volume software OpenFOAM 5.0 to simulate the three-dimensional temperature profiles within the wood. Dehydration experiment was conducted on the Douglas fir wood to verify the thermal model from room temperature to 200 °C. The thermal model was further validated by the full-scale fire experiment of the cross-laminated timber panel made of Spruce wood. It was found that both latent heat and pyrolysis heat have significant influence on the apparent specific heat capacity which further affected the thermal responses of wood. Moreover, the temperature is more sensitive to the latent heat than to the pyrolysis heat. The gas velocity is rather low in the dehydration and pyrolysis stages due to the low gas pressure. As a result, the gas convection seems to have very limited influence on the temperature progressions. Full article
