“…Wet connections rely on the splice of the reinforcement bars. They're usually achieved by a reinforcement lapping setting and an onsite concrete fill in the lapping dowel [10,11]. Though wet joints involve extra cost and time they enhance good ductility of the connection and do not hamper important movement in the connection [12].…”

“…In 2019 Scholars in Japan rate the performance of the wet as better or similar to the monolithic cast-in-situ intersection [13]. The dry connections are set up by means of the steel materials and are in most cases used for fixed connections [10,12]. Dry connections can be achieved in practical by bolting, anchoring or welding on site.…”

“…The grouted sleeve connection was found through much experimental work to withstand several earthquakes without undergoing any major deformation [35]. The wet connections are more preferred more than the wet in seismic zones because of their ability to allow movements within the connection setting [10]. No wonder, the PC structures now exist in seismic zones of Japan, China, Canada and etc.…”

Precast concrete structures have gained preference in the modern construction industry because of the multiple advantages they offer. The connection of precast members is an important aspect to consider in the design of structures with precast components. Grouted Sleeve connection, one of the famous connector types, is made of the trio of reinforced bars, high strength grouting materials and a ductile iron cylinder. This article compares the finding of recent experimental research findings on grouted sleeve connection and establishes the relationship between the three components of the connector to enhance the performance of the splicing agent. It is found that the tensile performance of the connector increases with the embedded length of the bar for a normal sleeve. An effective embedded length set between 6 and 8 times the diameter of the bar will maximize the tensile performance of the connector. The increase in diameter of the sleeve cylinder, the compressive strength of the grout and the length of the bar embedded and its surface will affect the bond performance and the mode of failure under tensile load.

“…Lu studied the precast prefabricated frame beam column connections with double sleeves [10][11][12], and the results showed that the double sleeve connections were superior to the cast-in-place connections in terms of strength and stiffness. Breccolotti's study indicated that although equivalent cast-in-place connections can meet the strength and stiffness requirements of cast-in-place structures, they do not address the problem of concentrated and difficult-to-repair damage inherent in cast-in-place structures [13,14]. Therefore, in recent years, non-equivalent cast-in-place connections corresponding to equivalent cast-inplace connections have been widely studied [15,16], especially the prestressed connections for the dry connection methods [17][18][19][20][21].…”

This paper introduces a novel type of connection that integrates unbonded prestressed strands (UPS) and mortise-tenon in an assembly frame structure (UPS-MTF). First, the damage process and failure modes of the joints under reciprocating horizontal loads were systematically analyzed using refined numerical models. The recommended values of the design parameters of the joints were derived from the parametric analysis results. Refined numerical modeling results reveal the diagonal compression strut mechanism within the core region of the joint. The diagonal compression struts model assists in establishing the theoretical calculation formula for the skeleton curve of shear stress–strain in the core region. Second, a genetic algorithm (GA) parameter was identified for the restoring force model of the core region to determine the parameters of the hysteresis rules. Finally, a macro-simplified analytical model of the joint was created based on the restoring force model of the core region, and parameter analysis was conducted to verify the applicability of this macro-simplified analytical model. The research results prove that the damaged form of the joint proposed in this paper originates from the shear and relative slip damage between the components in the core region. The axial compression ratio significantly affects the hysteretic performance of the joints, and the upper and lower limit values were identified for the axial compression ratio of the joints. The area and initial effective stress of the UPS exert a minimal effect on the hysteretic performance of the joint. Based on the method proposed in this paper for determining the restoring force model in the core region of the joints, the hysteresis curves obtained from the macro-simplified analytical model closely match the refined numerical analysis model results. This correspondence verifies the applicability of the macro-simplified analytical model.
