Abstract
Precast concrete buildings (PCB) offer several advantages, including swift construction, exceptional quality, enhanced durability, decreased formwork requirements, and reduced labour. However, it is crucial to effectively study the connections between the various prefabricated elements that make up the structure, particularly in the face of dynamic loads and seismic actions. Extensive research has been conducted to develop seismic-resistant PCB, underscoring the necessity of exploring research approaches, identifying trends, addressing gaps, and outlining future research directions. A thorough analysis was carried out on a literature set comprising 127 articles published between 2012 and May 2023, using a three-step research process that included bibliometric search, quantitative analysis, and qualitative analysis. The primary objective was to identify prevailing research trends and pinpoint current gaps that would contribute to the advancement of future research. The scientific mapping of authors' keywords revealed the correlation between PCB and topics such as dry connections, energy dissipation, optimal design, and progressive collapse, highlighting the diverse nature of current research in the field. Furthermore, the qualitative literature analysis demonstrated that frame and shear wall systems emerged as the predominant categories. This dominance can be attributed to the seismic performance reference being the traditional cast-in-place building approach. Nonetheless, this study brings attention to several notable research gaps. These gaps include the necessity to explore innovative, resilient structural systems in greater detail and the requirement for adopting state-of-the-art methodologies that facilitate decision-making processes in integrating PCB seismic safety and sustainability. This study provides a roadmap for future research projects and reports on the latest developments and trends in seismically safe PCB research.
