###### Abstract  
The introduction of a novel replaceable plastic hinge technology aims to enhance the performance of precast reinforced concrete (PRC) frames, particularly in seismically vulnerable areas where substandard structural systems are prevalent. This artificially controllable plastic hinge (ACPH) mechanism effectively localizes inelastic deformations to a detachable steel subassembly, thereby maintaining the integrity of the primary structural components. A numerical analysis was carried out on four distinct PRC frame configurations that utilized concrete and steel of inferior quality relative to contemporary standards. The frames underwent testing under a segment of the Mw 7.7 Kahramammaras ground motion, revealing that connections utilizing the ACPH not only reduce peak base shear but also mitigate cracking at beam-column interfaces, directing plastic strains towards replaceable fuse elements. The implementation of the ACPH also facilitates extended structural periods and localized plastic hinging, which serves to limit damage to essential members while expediting post-earthquake repairs. Comparative validation through prior subassembly tests confirms that this hinge exhibits a strong hysteretic response and ductile performance, surpassing traditional wet-joint connections in the context of substandard PRC frames. Overall, these results underscore the potential of standardized hinge modules in enhancing seismic resilience and supporting swift, economical rehabilitation of critical infrastructure. Thus, this proposed technology effectively tackles persistent issues related to low-strength materials in precast structures, presenting a practical approach to improving earthquake resilience and minimizing repair time and costs. p 2025 15 5629 13 May 2025 15 May 2025 1  
and commercial complexes, where the speed and dependability of construction are of paramount importance. The evolution of precast technology throughout history has been primarily influenced by the objective of minimizing on-site labor and formwork activities while ensuring consistent quality and uniformity [1]. Conventional cast-in-place concrete construction typically requires significant labor, extensive formwork setup, prolonged curing durations, and is vulnerable to fluctuations in environmental conditions during the curing process. Conversely, precast components can be manufactured in regulated settings, resulting in superior material strengths and more precise dimensional tolerances. Numerous developed countries have long acknowledged these benefits, culminating in the off-site production of comprehensive building systems, encompassing beams, columns, and facade components. Although precast construction offers advantages in terms of cost efficiency, rapidity, and material integrity, apprehensions persist regarding the ductility and seismic resilience of precast frameworks, especially at their junctions. Recent research has highlighted the seismic vulnerability of precast load-bearing wall systems. [PERSON] et al. [2] performed a probabilistic seismic evaluation of long-span precast industrial structures with wall systems, revealing that inadequacies in panel continuity and anchoring details might significantly affect the overall collapse probability. Their results highlight the need for comprehensive enhancements in several components of the PRC, beyond only the frame parts. Beam-column connections in PRC frameworks fundamentally differ from those in cast-in-place constructions. In a structure that has been cast monolithically, the continuity of reinforcement and concrete facilitates a relatively uninterrupted transfer of bending moments, shear forces, and axial loads throughout the beam-column junction. When exposed to seismic activities, this continuity aids in distributing stresses in a more consistent and ductile manner, although it remains susceptible to potential failure if not designed according to contemporary seismic criteria.
