“…For cracks that occur more tightly in the beam area for monolithic connections (BN) when compared to 2-post precast connections (BG-1) and 4-post precast connections (BG-2). In the column, especially the lower column, the cracks that occur are more for the BG-1 and BG-2 precast joints when compared to the monolith (BN) connection [19][20][21][22].…”

The beam-column connection plays an important role in the building structure, especially when the load is cyclic. The main problem that must be solved is the beam and column connection panels. The purpose of this study was to analyze the characteristics of the hysteresis loop of the displacement load relationship with the control displacement of the precast beam-column connection due to cyclic loading. The research method used is the experimental method with a measurable object design test and a special testing method. The results of this study indicate that normal concrete has a compressive strength of 26.43 MPa, while grouted concrete has a compressive strength of 36.97 MPa. The findings of this study also show that the bond stress grouted concrete increases by 102.4% from normal concrete for D13 diameter screw reinforcement, while for D16 diameter, the adhesive stress increases by 51.63%. The findings of this study also show that in the ultimate condition, the load obtained in the tensile load is 13.58 kN with a displacement of 87.58 mm, while the compressive load is 12.62 kN with a displacement of 88.30 mm. This study concludes that the behavior of precast beam-column joints with dowels is stronger in resisting cyclic loads.

“…Lago et al [12] proposed a dry prefabricated frame structure connection to couple the reinforcement of columns and beams and demonstrated its efficiency in reducing seismic drifts. Gennaro et al [13] tested an isolated single dowel connection and a refined one in a pushover experiment. Ding et al [14] put forward a dry connection with a bolt and claimed that the energy dissipation capacity of the proposed connection could be improved significantly with a higher strength grade for the bolt.…”

Prefabricated beam–column connections are the most vulnerable components of prefabricated buildings during earthquake events. The seismic performance of the beam–column connection is functional as the critical component plays a key role in structural safety. This study aimed to develop a novel hybrid prefabricated concrete (HPC) connection, combining with wet and dry connection techniques, to enhance the seismic performance of prefabricated concrete frames. A quasi-static experimental investigation was carried out to examine the seismic performance of the proposed connection. Two full-scale prefabricated connection specimens utilizing the proposed HPC connection and another code-defined monolithic prefabricated concrete (PC) connection were tested under cyclic loading, keeping the axial load on the column constant. The ductility, stiffness degradation, energy dissipation capacity, post-tensioned force, and residual displacement were obtained based on the experimental output. The results indicated that the HPC connection developed had high construction efficiency and better seismic performance than the conventional PC connection. The strength and energy dissipation capacity were significantly improved by up to 52% and 10%, respectively. The cracking and stiffness degradation were well-controlled.

This article investigated four concrete beam‐column connections experimentally, including an interior precast specimen, an exterior precast specimen and two corresponding cast‐in‐place (CIP) specimens. Longitudinal rebars of precast columns were connected by embedded bolt connectors, while longitudinal rebars of precast beams were welded in CIP core areas. These full‐scale beam‐column connections with axial compression ratio 0.5 were tested under reversed cyclic loading to estimate seismic behavior. The results revealed that failure pattern of all specimens was flexural failure which occurred at beam ends near column face. No obvious damage took place in core areas and columns. The hysteresis curves of all specimens were relatively plump, showing relatively good energy dissipation capacity. The difference of bearing capacity between precast specimens and corresponding CIP specimens was not greater than 5%. Displacement ductility of the interior and exterior precast specimens was 3.17 and 2.70, which was about 5.4% lower and 3.4% higher than that of corresponding CIP specimens, respectively. A degenerated four‐linear restoring force model was proposed for the precast beam‐column connections with bolt connectors in columns.
