Timber-Concrete Composite Structures: A Comprehensive Review of Emerging Trends, Advanced Modeling Approaches, and Future Research Frontiers for Sustainable Hybrid Construction

Abstract

Timber-Concrete Composite (TCC) structures represent a pivotal advancement in hybrid construction, combining the tensile strength and sustainability of timber with the compressive durability of concrete. This synergy has made TCC systems increasingly relevant in modern architectural and engineering applications, especially as the industry seeks efficient, eco-friendly solutions. This review traces the historical development of TCC technology and highlights its practical applications across residential, commercial, and infrastructural projects. Special focus is placed on the technical elements that define TCC performance, including material compatibility, shear connection mechanisms, and structural behavior under static, dynamic, and environmental loading. Recent innovations in modeling and design—ranging from finite element analysis to parametric and data-driven tools—are also examined, with attention to how these approaches are reshaping structural assessment and optimization. In particular, the integration of machine learning algorithms and advanced simulation workflows offers new possibilities for predictive performance modeling and adaptive design strategies. The review further explores fire resistance, acoustic performance, and long-term durability, with insights into how these factors influence code development and real-world implementation. Sustainability is a central theme, as TCC systems offer reduced carbon footprints, enhanced material efficiency, and alignment with life-cycle and circular economy principles. The role of TCC in modular construction and prefabrication is also discussed, alongside challenges in disassembly and reuse. Looking ahead, the review surveys emerging research directions, including the use of bio-based and recycled materials, robotic construction techniques, and digital twin technologies for real-time structural monitoring. By providing an integrated overview of material science, engineering practice, and technological innovation, this review serves as a comprehensive resource for academics, practitioners, and policymakers aiming to leverage TCC systems in the pursuit of resilient and sustainable built environments.
