“…However, these works focused their investigation on the influence of a limited number of geometric parameters of the modular interlocking blocks, since the current manufacturing industry has been mostly developed based on casting processes using modular casts. On the other hand, recent transformations in digital manufacturing, including additive manufacturing techniques to print masonry blocks [36,37] and concrete panels with parallel [38,39] and non-parallel [40] layers, as well as cutting stones with CNC machines [41], have enabled us to construct segmental shells such that each of their constituent blocks has a unique shape [38][39][40][41][42][43][44][45]. These promising manufacturing advancements have motivated architects and industrial designers, as well as civil, mechanical, and industrial engineers, both in academia and industry, to develop the design methods generating segmental assemblages composed of segments with complex shapes optimizing fabrication, construction process, etc.…”

Segmental arched forms composed of discrete units are among the most common construction systems, ranging from historic masonry vaults to contemporary precast concrete shells. Simple fabrication, transport, and assembly have particularly made these structural systems convenient choices to construct infrastructures such as bridges in challenging environmental conditions. The most important drawback of segmental vaults is basically the poor mechanical behaviour at the joints connecting their constituent segments. The influence of the joint shape and location on structural performances has been widely explored in the literature, including studies on different stereotomy, bond patterns, and interlocking joint shapes. To date, however, a few methods have been developed to design optimal joint layouts, but they are limited to extremely limited geometric parameters and material properties. To remedy this, this paper presents a novel method to design the strongest joint layout in 2D arched structures while allowing joints to take on a range of diverse shapes. To do so, a masonry arched form is represented as a layout of potential joints, and the optimization problems developed based on the two plastic methods of classic limit analysis and discontinuity layout optimization find the joint layout that corresponds to the maximum load-bearing capacity.

“…As demonstrated in series of studies by Dyskin and colleagues, all platonic solids are interlockable into a monolayer structure [180]. Truncated platonic shapes can also be assembled into planar [181] and even non-planar structures [182] using identical or varying size blocks [183] (see Table 1 and references within). The main feature of TI that distinguishes it from other interlocking types is the absence of special keys and connectors.…”

Modern economic, social and environmental challenges require a new type of construction that ensures resilience, low construction costs and ease of maintenance. Material production, manufacturing of structural elements and final assembly should minimise the environmental impacts, such as greenhouse emissions and waste production. This review aims to identify the key routes of research and development required to address the environmental challenges the construction industry faces. It outlines recent advances and highlights the rising opportunities. The strategies with great perspectives include 3D concrete printing, prefabrication and modular construction, mortarless construction, development and utilization of sustainable, smart and composite materials, renewable energy systems and automation technologies including the Digital Twin technology. Hybrid approaches that combine traditional and novel construction methods present the greatest potential. Overall, collaboration between stakeholders is crucial in driving innovation and successfully implementing these advancements.

Topologically interlocked assemblies have traditionally been explored to study properties such as strength, toughness and fatigue when applied axial compressive load. The interlocked assemblies are used in real-life applications ranging from the aerospace industry to the construction sector. This concept is generally applied to segmented blocks to study what parameters affect failure and how the failure occurs. The Segmented interlocked assemblies are investigated to optimize performance and weight compared to a monolithic design with poor strength characteristics. Strength to weight ratio is beneficial to applications where the efficiency of the product relies heavily on the weight. This study is performed on the 3D printed cubes with interlocking geometric slots, and the segmented cubes were investigated for failure through a three-point bending test under different conditions. The study used parameters such as speed of testing, lubrication between blocks, and the shape of the slots. This paper makes use of the Taguchi design of experiments in combination with grey relational analysis to optimize the parameters. Different lubrications were used to create a variation in friction between the blocks simply. After processing the data, it was concluded that the best condition was a circle shape, with lubrication #1 at an indenter speed of 10mm/min, followed by a circle and dry at 5mm/min. Triangle shape with lubrication #1 at a speed of 5mm/min was third in terms of the overall rank. According to the results, the worst-performing condition was a circle shape with lubrication #2 at a 1mm/min speed.
