“…Esmaeili et al [11] and Lachimpadi et al [3] stated that the precast reinforced concrete frame falls under the category of Industrialized Building System (IBS) but is constrained in its assembly, specifically in the precast beam-to-column connection (PBC). These constraints present various challenges and lead to the design of pinned connections that are inappropriate for moment-resisting frames (MRFs) in regions with high seismic activity.…”

“…The ability of construction industries to enter the global market relies on three fundamental factors: firstly, having technological advantages linked to robust construction technologies; secondly, deploying advanced management systems for activities such as scheduling, material tracking, and subcontractor organization; and thirdly, possessing the financial capacity to secure project financing from international financiers [1,[8][9][10]. Technology plays a pivotal role in propelling the construction industry to attain international standards, enabling construction companies to achieve sustained profitability and ensure balanced growth in the future [11]. The study encompasses an analysis of four countries: the United States, the United Kingdom, Australia, and Malaysia.…”

“…Consequently, negative perceptions, including high expenses, delays, supply shortages, subpar architecture, and outdated prefabricated housing, have adversely affected public opinion on IBS [2,9,14]. An innovative IBS block house has been developed, aiming to address the shortcomings of traditional IBS methods while showcasing its advantages to both construction stakeholders and the public [2,11,15]. This block house utilizing an IBS employs a precast reinforced concrete block system that is tailor-made to ensure the safety of occupants in the face of natural disasters and unforeseen risks.…”

Throughout history, the construction industry has been a significant contributor to construction waste, presenting an ongoing challenge in efficiently managing this waste to mitigate environmental pollution. The Industrialized Building System (IBS) stands out as a construction approach that utilizes prefabricated components made from various waste materials, implemented with machinery and formwork, leading to minimal waste production. The potential failure of IBS blockwork columns under lateral loads is a significant concern, and the deformation of these columns is crucial in assessing overall structural performance against lateral forces. This study focuses on examining the deformation and flexibility of components in IBS blockwork columns when subjected to lateral loads. Using Finite Element Modeling (FEM), a 1:5 scale prototype model of the dual-reinforced system IBS Block Work Column is analyzed. The IBS Block Work Column, comprising four prefabricated components assembled in the form of a crucifix plan to enhance lateral stability, is subjected to FEM analysis and experimental investigations. The study aims to explore the impact of four different shapes of reinforcement on deformation resistance. The findings suggest that employing a dual-reinforced system in the IBS Block Work Column enhances its resistance to lateral loads compared to a column with conventional reinforcement. Moreover, the assembled IBS Block Work Column exhibits greater stiffness than a single prefabricated component when subjected to lateral loads. Doi: 10.28991/CEJ-2024-010-01-020 Full Text: PDF

“…They demonstrated that the proposed system could prevent cracking efficiently and provide satisfactory seismic performance under sustained stress [20,21]. However, wet connections require long waiting times for the in situ casting and, hence, may lead to congestion and inefficiency in construction [22][23][24].…”

Prefabricated beam–column connections are the most vulnerable components of prefabricated buildings during earthquake events. The seismic performance of the beam–column connection is functional as the critical component plays a key role in structural safety. This study aimed to develop a novel hybrid prefabricated concrete (HPC) connection, combining with wet and dry connection techniques, to enhance the seismic performance of prefabricated concrete frames. A quasi-static experimental investigation was carried out to examine the seismic performance of the proposed connection. Two full-scale prefabricated connection specimens utilizing the proposed HPC connection and another code-defined monolithic prefabricated concrete (PC) connection were tested under cyclic loading, keeping the axial load on the column constant. The ductility, stiffness degradation, energy dissipation capacity, post-tensioned force, and residual displacement were obtained based on the experimental output. The results indicated that the HPC connection developed had high construction efficiency and better seismic performance than the conventional PC connection. The strength and energy dissipation capacity were significantly improved by up to 52% and 10%, respectively. The cracking and stiffness degradation were well-controlled.

“…PC building construction includes association rules of work activities, in particular, the beam-to-column connection, which involves pinned connections from the brief productions of moment resisting frames and has adverse effects on the cost and safety (e.g. ductility) (Chen et al , 2020; Esmaeili and Ahooghalandary, 2020). Depending on their stiffness [1], PBCs are classified as pinned or rigid connections.…”

PurposeThe purpose of this paper is to show that the growing global trend of quality assurance indicates the potential of precast concrete (PC) to improve construction quality and productivity, reduce wasteful construction, and achieve design standardization and to accelerate construction time. However, its current approach for dynamic characteristics, such as stiffness and displacement on beam-column connection system design, is not effective in achieving the required quality and operational requirements.Design/methodology/approachA design tool based on the literature and data analysis in product planning and safety is proposed for the practice of PC building construction.FindingsThe results reveal the need for improvement of PC building performance in the construction industry, especially for the beam-column connection system. The issues include improper design, improper specification and defective concrete and steel components compared to other manufacturing methods.Originality/valueA novel and sophisticated technique based on physical internet-enabled building information modeling (PI-BIM) is proposed to improve the planning process and safety for PC buildings in Malaysia.
