In civil engineering, carbon is typically regarded as a modern material to serve as reinforcement in concrete structures. Compared to steel reinforcement, it features two substantial benefits: It is not sensitive to corrosion, and has an enormously increased tensile strength. In contrast, carbon reinforcement is sensitive to lateral pressure and lacks the property of strain hardening. As a first step of establishing carbon reinforced concrete as a new building composite material, carbon reinforcement has basically served to replace the state‐of‐the‐art steel reinforcement. This target led to pioneering findings with respect to determining the material properties of the composite and developing advanced individual components. However, barely substituting steel by carbon does not allow to fully utilise the carbon's benefits while its disadvantageous properties reveal the limits of this approach. Instead, novel design principles are required to meet the material's nature aiming at appropriately using its beneficial properties.Currently, new construction principles are being researched for high‐performance building material combinations such as textile and carbon reinforced concrete. This paper provides an overview of baselines in the preliminary stages of this research. The overview includes history, inspiration, concrete matrices, non‐metallic reinforcement, structural elements, modelling, production, tomography, and sustainability. The objective of the study is to provide a baseline for the envisaged development of principles for future construction: radically new concepts for the design, modelling, construction, manufacturing, and use of sustainable, resource‐efficient building elements made of mineral building materials with the aim of entirely benefiting from the materials’ potential.This article is protected by copyright.

“…Experimental and numerical tests [20] investigated the in-plane and out-of-plane capacity of masonry walls composed of blocks with corrugated interfaces. Out-of-plane behaviour of osteomorphic blocks and interfaces with cross-shaped locks were also experimentally investigated by Dyskin et al [21] and Ali et al [22], respectively. Similarly, experimental and numerical investigations were carried out on the different behaviour of wooden joinery connections with different geometric properties [23][24][25][26].…”

Torsion-shear behaviour at the interfaces of rigid interlocking blocks in masonry assemblages: experimental investigation and analytical approaches

et al. 2021

Increasing interest has recently been devoted to interlocking blocks/interfaces capable to enhance the sliding resistance of masonry joints to external forces. In this framework, this paper deals with the assessment of the torsion-shear capacity of the contact interface between the lock and the main body of an interlocking block, assumed to have a cohesive behaviour. The interlocking block is a rigid unit which, on its faces, have square cuboidal locks keeping the adjacent/overlapped blocks together and preventing blocks from sliding. Two numerical approaches and a novel ad hoc experimental investigation are proposed to simulate the torsion-shear behaviour by applying eccentrical shear forces to the lock. First, concave, convex and corrected concave formulations provided by the literature for assemblages of rigid blocks with conventional planar joints are extended to model the interlocking block behaviour. Then, according to a second approach based on the discrete element method, the concave-shaped interlocking block is modelled by convex polyhedrons representing the lock and the main body of the block, considered as individual rigid units stacked over each other with a cohesive contact in between. A novel experimental investigation on the limiting pure shear and torsion-shear combinations at the lock interface made of cohesive material is also presented. Two different mortars were chosen to make the specimens, which were casted using 3D printed moulds, and different test configurations were set up to simulate shear and torsion-shear failures. The analytical and numerical results are compared with each other and against the experimental ones, with interesting remarks on the application of the different approaches.

“…Totoev [2] and Hossain et al [3] experimentally and numerically investigated the in-plane and out-of-plane behavior of the walls with corrugated joints. The out-of-plane behavior of masonry walls with osteomorphic blocks [4,5] and cross-shaped joints [6] were also studied, together with the more conventional interlocking constraints [7][8][9]. Fang et al [10], Sassu et al [11] and Cipollini et al [12] carried out several interesting numerical and experimental analyses on the structural behavior of wooden joineries with various shapes.…”

This paper presents a method to analyses the structural feasibility and assemblability of the masonry assemblages composed of interlocking blocks. Interlocking blocks with projections and depressions on their faces have relatively better structural performance comparing to the conventional blocks with flat faces, during and after the construction. Therefore, they can represent proper alternatives to the conventional blocks for the seismic retrofitting of unreinforced masonry structures. Structural soundness and assemblability of a model are both functions of the interlocking block geometry. The proposed methods enable the designer to adjust the shape of the interlocking blocks, while meeting the structural and assembling requirements. The paper first introduces an extension of the limit analysis to the assemblages with corrugated interlocking interfaces having anisotropic sliding behavior. Then, the work reformulates the extended limit analysis to develop a method to measure the structural infeasibility due to the lack of sliding resistance at the interlocking interfaces. This is called sliding infeasibility and the designer can minimize it during the shape exploration. Finally, an assemblability method is presented to check if the designed interlocking blocks can be assembled on the other blocks in contact. This method is added to the extended limit analysis and the sliding infeasibility measurement method in form of a geometric constraint that prevents modeling of un-assemblable structures.
