Special Issue Information

Dear Colleagues,

"New Trends in Innovative Building Materials and Structures" discusses recent advancements in materials and construction techniques that are reshaping the building industry. The issue highlights the development of sustainable materials like carbon fiber, metamaterials, cellular structures and self-healing concrete, which offer improved durability and environmental benefits. Additionally, it explores the integration of smart technologies in building design, such as sensors for real-time monitoring and adaptive systems for energy efficiency. The focus on modular construction and prefabrication methods is also emphasized as a means to enhance efficiency and reduce construction time. Overall, the issue underscores the importance of embracing innovative materials and technologies to meet the evolving demands of modern construction projects.

By adjusting the two wall angles of the orthogonal hybrid honeycomb (OHH), the tunable Poisson’s ratio change from negative to positive values and the variation in stiffness can be achieved. To effectively analyze its static and dynamic characteristics, a two-dimensional equivalent Kirchhoff–Love model (2D-EKM) is established based on the variational asymptotic method (VAM).This model aids in effectively addressing the complexity arising from anisotropy. The obtained equivalent orthotropic properties are validated through unit-cell uniaxial compression tests and three-point bending experiments on 3D-printed specimens. The numerical simulation results suggest that the VAM-based 2D-EKM can predict the in-plane and out-of-plane static behaviors of OHH panels, with a maximum error below 10%. Particularly in the dynamic analysis of a four-sided fixed OHH panel, the analysis time required by 2D-EKM is only 0.37% of that needed for the 3D FE model. The OHH-ZPR panel exhibits exceptional resistance to deformation, with a maximum deformation under in-plane tension reaching only 27% of that in the OHH-PPR panel. Moreover, each 1% increase in the height–length ratio results in a respective increase of 275.62% and 281.93% in equivalent bending stiffness along both directions. This highlights that enhancing this ratio effectively boosts the fundamental frequency compared to the elastic modulus ratio, effectively prevents low-frequency resonance occurrences, and offers vital insights for the design and optimization of OHH panels.
