STRUCTURAL SOLUTION OF TIMBER-CONCRETE WALL PANEL FOR ECOLOGICAL BUILDINGS

Problem statement. The scale of destruction caused by military actions requires the development of innovative construction solutions. Traditional construction methods that use materials with high carbon footprints are becoming environmentally unsustainable. Of particular relevance is the search for alternatives that combine rapid installation, material availability, and minimal environmental impact. Solving this problem requires a comprehensive approach that considers both the technical characteristics of materials and their environmental efficiency throughout the entire life cycle. The purpose of the article is the development of a wall panel structural solution that meets requirements for both environmental efficiency and thermal insulation performance. Conclusion. The proposed structural solution for a timber-reinforced concrete wall panel consists of three layers: 1) an inner load-bearing layer made of cross-laminated timber; 2) an outer concrete layer with recycled aggregate, designed to protect internal layers from environmental exposure and serve as a base for building facade finishing; 3) a thermal insulation layer composed of natural bio-based materials. The study includes systematic analysis of thermal conductivity characteristics and life cycle emissions of natural insulation materials, with determination of optimal insulation thickness to achieve required thermal resistance. Recommendations are provided for selecting natural insulation materials based on environmental performance indicators. This panel design combines the advantages of timber, recycled concrete and bio-based insulation, making it particularly suitable for rapid reconstruction of damaged infrastructure while simultaneously reducing the environmental impact of construction. The structural solution incorporates conventional manufacturing and installation techniques, facilitating practical implementation in construction projects.
