###### Abstract
steel plates at the beam-column intersection significantly alleviates initial damage, thereby enhancing seismic resilience. [PERSON] and [PERSON] [13] determined that the seams of connections in monolithic precast joints play a critical role in the progression of damage, highlighting the necessity for refined joint detailing. [PERSON] et al. [14] asserted that corrosion in grouting sleeve connections compromises the seismic performance of precast joints, thus emphasizing the vital importance of designing durable joints. These observations corroborate that beam-column connections are among the most susceptible areas in precast reinforced concrete systems and further validate the requirement for mechanisms such as the ACPH, which are engineered to concentrate damage within a sacrificial component while safeguarding the adjacent structural elements. Initial strategies are aimed at enhancing the ductility of precast connections adopting fully grouted sleeves that interconnect reinforcing bars across the joint or utilize welded plates that secured beam bars to the column surface. Although these techniques can produce resilient connections when meticulously detailed, they may not consistently withstand the inelastic demands imposed by intense seismic activity without incurring substantial damage that jeopardizes the potential for reuse or repair. Indeed, the concept of damage localization has garnered heightened significance: should the plastic hinge develop in a predetermined area that is amenable to repair or replacement, the remaining structural elements may largely remain undamaged, thereby facilitating and accelerating post-seismic repairs. The idea of a replaceable plastic hinge exemplifies this damage-mitigation strategy. By confining inelastic behavior to a specifically designed connector, the primary beam and column elements can stay within an elastic range, even amidst severe seismic shaking. The underlying justification for prioritizing a replaceable plastic hinge over a monolithic emulation is in part driven by practical requirements for resilient structures that can be swiftly reinstated following seismic events. Facilities located in industrial zones or essential infrastructures such as hospitals and emergency shelters typically cannot endure protracted periods of inactivity for repairs. Conventional restoration methods for compromised beam ends in a monolithic configuration may necessitate partial demolition, shoring, re-bar splicing, and on-site re-casting, all of which are time-intensive processes. Alternatively, the utilization of a specially engineered steel device that can be bolted or otherwise conveniently affixed and detached at the end of the beam allows for the concentration of damage from repetitive deformations within that device, which can be replaced within a timeframe of hours or days. This concept lies at the foundation of the artificially controllable plastic hinge (ACPH). Essentially, the ACPH is based on a weak-joint/strong-component philosophy, ensuring that the replaceable steel element yields or fails prior to the beam or column, thereby preserving the integrity of the primary structural components. Engineers gain an advantage as this device can be designed and detailed to meet both strength and deformation capacity criteria while also facilitating controlled energy dissipation. Another significant dimension of the context pertains to the obstacles associated with the analytical and experimental verification of these principles. The intricacies inherent in precast connections necessitate sophisticated nonlinear analyses, including finite-element modeling incorporating damage plasticity for concrete or enhanced joint macro-models that effectively encompass slip, localized strain concentrations, and strain-rate phenomena [15].
