“…This specimen configuration allows determining accurately the contribution of UHPFRC cover on an isolated portion of lap splices in tension, which could represent a thin UHPFRC layer used for strengthening poorly detailed lap splices [17], or a UHPFRC lap splice joint between precast elements [22].…”

“…It has been shown that the use of UHPFRC in the lap splice region allowed to: (1) strengthen seismically existing bridge piers with poor detailing at their bottom [13][14][15][16][17][18][19], (2) significantly reduce the joint lengths between precast-slab lengths for building [8,20] and bridges construction [21,22], (3) create an alternative proposal for moment-resisting frames (beam-column) in precast building with innovative joint connection [23].…”

“…However, no study on lap splice specimen under tension with the UHPFRC has been undertaken to examine the influence of its tensile properties on the bond performance of the joint. In addition, the studies on an alternative connection between precast elements [8,21,22] were limited to small bar diameters (d b 6 20 mm). This paper presents the results of an investigation on the behaviour of tensile lap splice specimens with different UHPFRC mixes, on long embedded length and low confinement.…”

“…In addition, static response modeling of the joint was performed through finite element method (FEM) analysis [7]. Various reinforcement shapes and types as well as various lapped splice constructions, including those using U-bars, were used as variables in the evaluation of the structural performance [3,[8][9][10]. In addition, strength tests on connection systems were performed using the flange combinations of the Bulb-Tee girder, with analysis of crack propagation and system strength [11].…”

An Experimental and Analytical Study on the Deflection Behavior of Precast Concrete Beams with Joints

Abstract:The use of precast concrete modular construction in the replacement and rebuilding of old structures has recently increased. However, the joints between modules in this type of construction exhibit special behavior that should be considered when analyzing the behavior of modular members. Both stability and serviceability should be studied; however, existing research has only addressed the former. Research regarding serviceability, involving deflection and crack development and propagation, is lacking. This study considers the difference in strength between on-site cast and precast segmental concrete to accurately evaluate the deflection of precast concrete flexural members with joints within the lapped splice. In addition, to reflect an initial crack, the deflection is calculated and evaluated by reflecting the effect of tension-stiffening and subsequently redefining the attached transmission lengths of the left and right sides of the cracked surface as a new cracked region. As a result of explicitly including joint behavior which is considered attached transmission length and characteristic by concrete strength, a more accurate calculation of deflection is developed.

“…Three types of joint reinforcement shapes were suggested using the shape of a joint, the type and arrangement of reinforcements, and a lap splice as the variables, and a performance test was performed [10,11]. Moreover, the longitudinal and transverse performances of a U-bar precast joint were verified [12].…”

Abstract:This study involved applying a design code change on a modular bridge design. The top flange of a modular T-girder bridge was examined by the Korean Highway Bridge Design Code Limit State Design (2015) and was compared with the Korean Highway Bridge Design Code (2010) in terms of the stability under the bending moment. In addition, the cross-sectional height and reinforcement amount were re-designed to obtain a safety factor similar to the original code. The reinforcement arrangement and development of the transverse joints were examined in the section considered. The result indicated that the application of the Korean Highway Bridge Design Code Limit State Design (2015) increased the bending moment safety factor and decreased the width of the transverse joints. The results of the re-design with respect to a safety factor similar to that in the Korean Highway Bridge Design Code (2010) indicated that it was possible to reduce the cross-sectional height and reinforcement amount. Furthermore, based on the obtained section, the results revealed that the width of the transverse joints could be reduced by changing the arrangement of lap splices from the straight bar to the loop.
