“…The connection of PC components is a key link in the quality assurance of prefabricated buildings. During the construction process, the construction staff confirmed that the key operation has been completed based on the grout left in the grouting hole [4]. However, it is more difficult to inspect the hole, so it is challenging to guarantee the integrity of the key node.…”

Prefabricated concrete (PC) buildings are a relatively new type of housing construction. It is not only necessary to ensure the quality of PC components, but also to guarantee the quality of key technical nodes of construction. Based on specific engineering project cases, this article proposes solutions and methods for the key technical nodes of prefabricated concrete construction, and proves their feasibility and effectiveness through practical applications. It illustrates an optimization of prefabricated concrete construction technology to improve construction quality.

“…Conventional RC slabs usually suffer from severe damage due to earthquakes. (Li, Qi, &Teng, 2020) In this study, a novel prefabricated beam-to-column steel joint suitable for precast concrete structures was developed. The proposed steel joint with dampers could replace cast-in-situ concrete beam-to-column joints in precast concrete structures.…”

Building projects purvey many advantages by the use of precast concrete frame structures in expeditious construction, lowering formwork, upgrade construction condition, carbon emission depletion and environmental conservation. The behavior of precast concrete structures are subjected to different loading conditions. Loading conditions depend on type, location and the connections between elements. Exiguous strength and indigent ductility of the beam column joint create the weakest link in the structure, which the reason for failure of any kind of structures. So various literature have been reviewed to ensure the reliable connections between the beam column joints.

Li et al (2020a) studied the seismic performance of prefabricated concrete beam-column joints, with better energy dissipation. Hu (Hu et al, 2020) has carried out the low cycle reciprocating test on three 1/2 scale prefabricated structures, and found out the prefabricated members can achieve better seismic performance.…”

To study the cyclic behavior of partially precast steel fiber high-strength concrete columns with high-strength steel bars, four full-sized square column specimens were fabricated and tested under constant axial load and horizontal cyclic load. The effects of the strength of precast concrete shell and the diameter of cast-in-place column core were analyzed in detail. The results show that partially precast steel fiber high-strength concrete columns have good seismic performance and deformation ability. Compared to the concrete column with lower strength of precast concrete shell, the concrete column with higher strength of precast concrete shell showed higher bearing capacity and energy dissipation capacity while lower ductility. Moreover, with the increase of the diameter of cast-in-place column core, the bearing capacity and the deformation ability of the specimen decreased. Finally, based on the experimental research and theoretical analysis, a calculation model for predicting the maximum bearing capacity was proposed, and the results obtained from the formulas were in good agreement with those from the experiments.
