“…To date, numerous studies [6,7,[24][25][26][27][28] have reviewed the performance of prefabricated modular buildings, with several focusing on the structural behaviour of multi-storey/high-rise modular structures [8,[29][30][31][32][33]. There is a consensus among researchers that IMC systems are paramount in the structural performance of steel MBSs, many emphasising the lack of reliable connections between modules as a crucial limitation.…”

“…Thai et al [30] highlighted an extremely low application of modular construction in high-rise buildings and illustrated fifteen connections, partly attributing the hesitation and lack of confidence felt among construction professionals about this technology to the lack of strong inter-module joining techniques. Chen et al [8] summarised the recent advancements of structural systems, design techniques and illustrated more than thirty IMCs, insisting also on the importance of manufacturing and constructional aspects such as ease of manufacturing, ease of installation, particularly the difficulties of fixing the fourth modular unit at the internal joint due to lack of access. Rajanayagam et al [42] and Nadeem et al [43] focused on some of the existing IMCs and emphasised the role of automated and semi-automated joints in solving constructional challenges in MBS.…”

“…So far, volumetric modular construction has adopted a wide range of structural materials (Fig. 2) for its chassis, which have been typically divided in the literature [3,[6][7][8] into timber, concrete, steel (cold-formed and hot-rolled), composite or a combination of these. The choice of material is usually governed by the height and structural system of the building, with timber and light-gauge steel typically used in low-to-mid-rise applications (Fig.…”

The paper is devoted to modular buildings as а current topic of modern construction. A significant number of studies on this topic have appeared both in Russia and abroad in last years. It is necessary to classify modular buildings and highlight their design features to systematize the research. The main distinguishing feature of modular construction is the erection of a structure from volumetric modular blocks manufactured at the factory, each of which must also fully meet the requirements of functional, technical, economic feasibility and architectural expressiveness. Steel or wood is a common materials for modular constructions. Steel modular buildings have become more widespread due to their greater bearing capacity, so the paper provides a classification of modular buildings with a steel structure. Modular buildings are classified according to the following features: structural system of the building (arrangement and load transmission from one module to other); framework of modules (bearing structures of individual modules); nodal connections. There is two types of nodal connections: intermodular (joints of modules to each other) and intramodular (joints of beams and columns inside the module). Based on a review of literature sources and an analysis of advantages and disadvantages, the most common structural solutions for modular buildings in the Russian Federation were identified: buildings from stacked modules with support columns, intermodular joints on welding and welded intramodular joints. However, this provision does not limit research on modular buildings of other design solutions.

“…Continuously supported: Continuously supported or four-sided modules are supported on their longitudinal sides, which bear on the walls of the modules below. Continuous-supported modules are divided into a lightweight load-bearing wall system and a massive load-bearing wall system based on the type of sidewall support system [109]. Monolithic load-bearing wall modules are commonly used in concrete buildings, in which the concrete walls are used to transfer gravity loads to the foundation and resist the lateral loads [110].…”

Modular timber construction embodies a pioneering and eco-friendly methodology within the building sector. With the notable progress made in manufacturing technologies and the advent of engineered wood products, timber has evolved into a promising substitute for conventional materials such as concrete, masonry, and steel. Beyond its structural attributes, timber brings environmental advantages, including its inherent capacity for carbon sequestration and a reduced carbon footprint compared to conventional materials. Timber’s lightweight nature, coupled with its versatility and efficiency in factory-based production, accelerates modular construction processes, providing a sustainable solution to the growing demands of the building industry. This work thoroughly explores contemporary modular construction using wood as the primary material. The investigation spans various aspects, from the fundamentals of modularity and the classification of modular timber solutions to considerations of layout design, structural systems, and stability at both the building and module levels. Moreover, inter-module joining techniques, MEP (mechanical, electrical, and plumbing) integration, and designs for disassembly are scrutinized. The investigation led to the conclusion that timber modular construction, drawing inspiration from the steel modular concept, consistently utilizes a structural approach based on linear members (timber frame, post-and-beam, etc.), incorporating stability configurations and diverse joint techniques. Despite the emphasis on modularization and prefabrication for adaptability, a significant portion of solutions still concentrate on the on-site linear assembly process of those linear members. Regarding modularity trends, the initial prevalence of 2D and 3D systems has given way to a recent surge in the utilization of post-and-beam structures, congruent with the ascending verticality of buildings. In contrast to avant-garde and bold trends, timber structures typically manifest as rectilinear, symmetric plans, characterized by regular and repetitive extrusions, demonstrating a proclivity for centrally located cores. This work aims to offer valuable insights into the current utilization of modular timber construction while identifying pivotal gaps for exploration. The delineation of these unexplored areas seeks to enable the advancement of modular timber projects and systems, fully leveraging the benefits provided by prefabrication and modularity.
