“…Despite the widespread application [9][10][11][12][13][14][15][16] of Prefabricated Partition Walls in various sectors such as Commercial Buildings, Residential Projects, Industrial Facilities, and Transportation Infrastructures, there is a notable scarcity of research examining the mechanical characteristics and the corresponding influencing factors of these walls. For the Prefabricated Partition Walls, the rationality and economic feasibility of these new sub-structures need to be verified.…”

Considering the factor of wind load, this study explores the engineering application of prefabricated assembled partition walls in underground stations. Using the finite element analysis software ANSYS, we simulate the displacement deformation and mechanical behavior of the assembled partition wall in the station under the action of wind load. At the same time, the mechanical characteristics of the assembled partition wall under the consideration of only self-weight factors are also used as a comparison to further analyze the main cause of partition deformation. We also extract the displacement data of the assembled partition wall in actual engineering and compare it with the numerical values obtained from the simulation software, providing theoretical support for actual engineering, and verifying the feasibility of ANSYS in engineering applications. The following conclusions are drawn self-weight is the main cause of partition deformation; the position and size of the holes directly affect the structural performance of the wall; the prefabricated assembled wall can meet the actual engineering needs of the subway.

“…The multifunctional, innovative building element was developed through different studies, starting with the structural one and was optimized through the hygrothermal, energy, acoustic and fire performance studies [10]. Its main form is now finalized; it concerns a composite panel, composed of two lightly reinforced concrete plates, 5cm thick each, which are positioned on either side of vertical (and occasionally diagonal) metal hollow elements.…”

Although modern prefabricated buildings may offer many advantages, such as a significant reduction in cost and time, improved quality and accuracy in manufacture, easy dismantle and reuse of its components, etc., they have not gained the attention they deserve in the construction market yet. In this paper, a holistic approach for the formation of prefabricated buildings of advanced performance is presented. Within this context, a new, innovative prefabricated building element is developed, designed to exhibit optimized structural, hygrothermal, energy, acoustic, fire and environmental performance. The improved properties of the building element are ensured by the proper configuration of the layers that compose it with respect to the design objectives; for example, in order to support the heat storage and the control of indoor temperatures, the integration of PCMs in the element's layers is investigated. Furthermore, in order to indicate the contribution of the new building element to the sustainability of the overall construction, the performance of a building formulated with the new element is analyzed in terms of energy and environmental behaviour. The new building element and construction system are expected to systemize the prefabricated element's production, leading eventually to the improvement of the building quality, as well as to the reduction of time and cost of building's erection. In parallel, the new certified and optimized building performance will increase the share of prefabricated buildings in the Mediterranean countries, where housing needs are gradually growing, while at the same time, energy efficient and environmentally friendly construction will be promoted.

In recent decades, steel frames infilled with precast load-bearing walls have been successfully employed as lateral load-resisting structural systems in high-rise buildings. This is due to their structural efficiency as outer and major inner facades and to the higher construction speed of the building. This paper presents a detailed experimental investigation of a sustainable, prefabricated, composite structural wall system, using a representative test model named the Precast Concrete Steel Panel-Infilled Steel Frame (PCSP-ISF) in full-scale dimensions and subjected to in-plane cyclic loading. A series of experiments was conducted on critical structural specimens, including three-point bending, concentric axial compression, and diagonal compression, together with additional cycling loading tests on steel connection joint specimens, with the aim of validating the reliability and the structural response of the connections. The resulting test data and the observed failure mechanisms are discussed carefully to optimise the sustainable structural performance of the system. A theoretical approach for the evaluation of the shear capacity of the total frame system is also discussed to expand the experimental results for several numerical and experimental research cases. The failure mechanism of this module was formed by a combination of developed plastic hinges on the steel joints and diagonal cracks on the concrete panel. The obtained hysteretic behavior of the system at a parameter with major impact is mainly analysed and discussed. The outcomes indicate a satisfactory and sustainable seismic performance of the PCSP-ISF model, indicating that it can be a very promising lateral load-resisting system for earthquake-prone regions.
