“…Although research to date has proved sufficient moment transfer of the connection, it is not recommended for high seismic areas that require plastic hinging of the connection (Culmo 2009). To promote the use of grouted duct ABC column connections in high seismic areas, a refined design equation based on all available test data, and building standards was determined by (Tazarv et al 2021).…”

Bridges are an essential part of every road and transportation system, and all countries must build bridges to improve their infrastructure. Accelerated bridge construction (ABC) is an innovative approach that has been noticed in recent years to facilitate and accelerate the process of building, repairing, or replacing bridges. This paper underscores the significance of ABC in bridge construction, focusing on its potential to offer speed, safety, and enhanced longevity for bridge pier. Through a comprehensive exploration of prefabricated elements and systems specific to bridge piers, insights into their applicability, advantages, and limitations are presented. A special section is dedicated to the investigation of pier connections under seismic loads. Furthermore, the review contrasts ABC with traditional construction methodologies, highlighting areas of excellence and potential improvement for ABC.

“…It is acknowledged that the connections between precast segments are critical for creating structural continuity, thus impacting the seismic behavior of the structure during extreme ground motion. To this end, various connection types between segments are applied to strengthen the precast pier's seismic performances, such as grouted splice sleeves [6][7][8][9], grouting corrugated pipes [10][11][12], grouted pockets [13,14], grouted ducts [15], and post-tensioned tendons [16,17].…”

Owing to the advantages of accelerated construction, reduced traffic disturbance, and enhanced quality control, precast segmental two-column bents are extensively utilized in urban and highway bridges, particularly in areas of low-to-medium seismicity. However, the application of this technique in high-seismicity regions is limited owing to insufficient knowledge about the seismic performance of such precast bents. To address this, the present study investigates the seismic performance of precast segmental two-column bents, focusing on the connection of “grouted splice sleeves and grouted central tenon”, namely the proposed GSS-GCT connection. For this purpose, three large-scale two-column bent specimens were fabricated and subjected to quasi-static cyclic tests: one cast-in-place bent, one precast two-column bent with conventional grouted splice sleeves, and another with the GSS-GCT connection. The benefits of the GSS-GCT connection under high seismic activities were demonstrated regarding lateral load-carrying capacity, displacement ductility, energy dissipation capacity, and residual displacement. Moreover, five levels of damage states were qualitatively and quantitatively divided based on experimental observation, which can be evaluated with lateral displacements. Furthermore, seismic assessments of the two-column bents were obtained using the capacity spectrum method. The proposed GSS-GCT connection could significantly improve the seismic performance of precast segmental two-column bents under high-level earthquakes.

Considering the complicated joint details and installation difficulties of beam‐column joints, a novel type of precast joint that utilizes grouted corrugated metallic ducts was proposed. Four full‐scale specimens were prepared and subjected to the low cyclic loading test, including two precast specimens (interior beam‐column joint and exterior beam‐column joint) and two cast‐in‐place specimens for comparison. The seismic behavior of the joint was evaluated based on failure modes, hysteretic behaviors, ductility, bearing capacity, and energy dissipation. From the test results, all specimens experienced bending failures at the beam end, which kept the plastic hinge away from the joint core area. The precast assembly joints showed excellent seismic behavior, especially in terms of the bearing capacity, ductility, and energy dissipation capacity, which are better than the cast‐in‐place ones. The bearing capacity measured for each specimen was greater than the design standard, indicating that the joints are reasonably designed, and the members are safe and reliable. Parametric analysis was also conducted by finite element modeling and design advice was given accordingly.
