Special Issue Information

Dear Colleagues,

Multifunctional building materials—capable of thermal regulation, energy harvesting, moisture buffering, self-sensing, self-healing, and enhanced durability—are reshaping how we design envelopes and load-bearing systems for low-carbon, climate-resilient buildings. Recent advances span phase-change-material (PCM)-enhanced components, aerogels and vacuum insulation, bio-based and recycled composites, self-sensing cementitious matrices for in situ monitoring, and building-integrated photovoltaics (BIPVs). Together, these technologies target both operational and embodied impacts across the building life cycle. This Special Issue seeks contributions that connect material design and processing with rigorous performance verification and modelling, from lab to field.

We welcome studies covering the following:

  • Synthesis, processing, and microstructural tailoring of multifunctional materials;
  • Comprehensive characterisation using destructive (e.g., mechanical/fracture, fire, durability) and non-destructive methods (e.g., ultrasonics, impact-echo, impedance spectroscopy, acoustic emission, SHM);
  • Multi-physics and multi-scale models (heat–moisture–mechanics–electrical), digital twins, and data-driven/AI frameworks;
  • Hygrothermal and thermo-mechanical simulations at component and whole-building levels;
  • Life-cycle/embodied-carbon, techno-economic, and circularity assessments, including retrofit case studies.

Original research articles, reviews, and short communications are invited. The Special Issue aims to bridge materials science, structural engineering, and building physics to accelerate deployable, verifiable, and truly sustainable solutions for new and existing buildings. The scope aligns with current progress in PCMs, BIPV, self-sensing cementitious materials, and LCA/hygrothermal modelling. I look forward to receiving your contributions.

This study explores the potential of non-destructive methods for diagnosing timber structures, with a primary focus on maximising the capabilities of the resistance-drilling technique. Laboratory tests were performed on spruce wood specimens, the most commonly used construction timber in Central Europe, prepared across a wide range of moisture contents (0–53%) to assess the influence of moisture on resistance-drilling characteristics. The resistance micro-drilling (RM) characteristic was found to be independent of moisture content (coefficient of determination close to zero), confirming that resistance drilling provides stable results under varying in situ moisture conditions. In contrast, wood density and the RM characteristic were strongly correlated, with coefficients of determination of R2 = 0.87 for moisture contents between 0% and 30%, and R2 = 0.90 for the 8–18% moisture range typical of timber in service. Based on these relationships, two linear conversion equations were developed (ρ = 1.685·RM + 183.85 and ρ = 1.982·RM + 135.15, respectively), enabling estimation of spruce wood density directly from RM values. Compressive strength parallel and perpendicular to grain decreased with increasing moisture content up to the fibre saturation point, beyond which the reduction in strength plateaued. Full article

Concrete structures often develop penetrating cracks due to the initiation and propagation of local cracks during service, which may lead to the fracture and failure of the entire structure. The propagation modes and laws of cracks in structural members are closely related to the safety of the overall structure. Conducting research on crack propagation and predicting crack propagation paths for cracked structures can provide technical support for the safety design and reinforcement of structures. Based on the basic framework of the extended finite element method (XFEM), this paper develops a user-defined element (UEL) for ABAQUS using the level set method, and simulates in a two-dimensional space the crack propagation in concrete beam bending tests with the self-developed UEL and the built-in XFEM module of the software. The solution results of the self-developed UEL are consistent in trend with those of the XFEM module, yet the cracks simulated by the XFEM module can only propagate along element boundaries and cannot cross elements, and the accuracy of its results is highly dependent on mesh size. The crack tip simulated by the self-developed UEL can stay inside the element, and the simulated crack propagation paths show a higher degree of agreement with the experimental results. The correctness of the UEL is verified through comparative analysis with the results of the four-point bending tests of concrete beams and the XFEM module of the software. The UEL developed in this paper can effectively predict the crack propagation paths of concrete beams and reveal the multi-crack propagation laws of concrete beams. Full article
