“…A broader concept of 3D printing technology, which could be employed for structural component manufacturing, also shows the great potential in manufacturing advanced protective structural components. In recent years, various protective structure/components, such as origami structures [39], meta-material/structures [40,41], auxetic structures [42,43], and nature-inspired structures [44] etc., which are different to manufacturing using conventional methods, becomes achievable using 3D printing technology. These structural components could be assembled to structures to improve their hazard resistance against blast and impact loadings.…”

The building and construction industry is a traditional industry that features high-capacity investment, long return period, high environment impact, and low technology demand in the past decades. With the fast development of technology and the demand for environmental sustainability, it is inevitable for the building and construction industry to embrace the revolution of technology. Intelligent construction is developed in light of advanced technologies including advanced computing technology, 3D design and manufacturing, automation and control, sensing, unmanned aircraft, and autonomous intelligence. It is also closely integrated with using perceived, analytical, decision-making coordination for building construction with perceived intelligent execution technology in the processes. Currently, there is no consensus definition on “intelligent construction” despite its rapid development. This paper reviews existing and current development in intelligent construction focusing on the following three aspects: (a) new structural forms, which are innovative and with potential or are being applied to automated and mass manufacturing/construction; (b) automated and intelligent construction system; and (c) advanced structure sensing and monitoring technology. These three components do not compromise the entire aspects for intelligent construction, but they have no doubt are the core elements for intelligent construction towards future building systems.

“…Various other concepts were developed within the broader field of meta-materials for the same scope. Among them are plate-like meta-structures for explosions' vibration attenuation [54], resonant structures in resin matrixes for the mitigation of blast waves [55], elastic meta-materials for blast wave impact mitigation considering non-linearity [56,57], negative effective mass [58] and locally resonant woodpile meta-materials for impact and blast mitigation [59]. Despite the significant interest in the development of meta-material concepts for structures' blast protection, a gap in the designing of meta-materials specifically for EIs and pipelines is observed.…”

The current study investigates the capacity of the proposed meta-material layout for the blast protection of above-ground steel pipes against explosions. The philosophy of the meta-material layout’s design is described adequately, and the 1D periodic structures’ theory is adopted for the analytical prediction of the layout’s band-gaps. The special characteristics of the blast loading are explained, and specific time-related parameters are calculated. The layout is tested numerically for nine explosion scenarios of various magnitude via the finite element program ABAQUS, and the CONWEP model is selected for the simulation of the explosions. The results demonstrate a significant reduction in the maximum displacements developed on the pipe’s spring line and crown within a blast loading. This study composes an extension of the author’s previous research on buried steel pipes and surface explosion, advancing now the applicability of the meta-material layouts for the cases of above-ground steel pipes towards explosions and blast hazards. The outer goal is the investigation and the further spreading of the beneficial exploitation of meta-materials concepts for the scope of the pipelines’ effective blast protection, readdressing that this way is a major hazard for this type of structure and a gap in the current literature.

Wave propagation in nonlinear acoustic metamaterials (NAMs) has attracted broad attention. While showing the possibility of achieving low-frequency and broadband vibration suppression, most existing work focuses on harmonic waves. In this paper, we study the impact wave propagation and its mitigation in a nonlinear metamaterial beam. Thorough numerical analyses show that strongly nonlinear acoustic metamaterials can entail effective attenuation of impact waves in an infinite structure and the impact vibration in a finite structure with a much higher efficiency than what can be achieved in their linear counterparts. The attenuation properties, underlying mechanisms and the influence of key system parameters are clarified. Results show that the observed attenuation is dominated by the nonlinearity-induced self-broadening of the bandgaps whose bandwidths adaptively expand with the propagation distance/time, as a result of the amplitudedependent nature of the band gaps in a NAM. In a finite NAM structure, significant attenuation of the impact vibration can be achieved, outperforming the corresponding linear cases. These findings shed lights on new physics relating to NAMs and might inspire their further study and application.
