In the prestressed composite girder bridges, the shear connectors will transfer a portion of prestress to the steel girders.However, more prestress is preferred to be remained in the concrete slab to improve its anti-cracking behavior and serviceability performance. A Partial Connection-Prestressing (PCP) method is proposed in this paper to decrease the prestress transferred to steel girders. The partial connection is achieved by applying Rubber-Sleeved Studs (RSS) in the prestressed concrete slab in the negative moment region. Since there is no experimental research regarding PCP method in continuous composite girders, two continuous girders specimens were tested under four-point static load to evaluate their mechanical performance. The test results showed that without decreasing ultimate strength and overall stiffness of the steel-concrete composite girders, the PCP method enhanced the cracking load by 3.1 times. Besides, only 12.5% of the prestressing force was transferred into the steel girder at the internal support section with PCP method, while that in girder without PCP reached 25.9%. Thereafter, to elucidate the partial interaction effect and prestress effect on continuous girders' mechanical behavior, numerical models were developed and calibrated with the test results. It was revealed in the numerical analysis that compared with normal composite girder, applying RSS or prestress alone can improve the cracking load respectively by 11.8% and 157.0 %, while the figure increases to 234.3% when applying RSS and prestressing at the same time. The results indicate that applying RSS in the negative moment region can effectively increase the prestressing efficiency in the concrete slab as well as enhance the bridge serviceability and durability.

“…Different to HRM, VRM is challenging and risky because the force of the rotating system varies due to the position change of superstructure. Finite element method (FEM) is a useful tool to simulate stress and deformation during construction process and analyze the strength and stability of various bridge components [8][9][10][11][12]. Ma et al [13] simulated the rotating structure in three dimensions of a concrete-filled steel tube concrete basket arch bridge, and the most unfavorable stress conditions were determined.…”

The vertical rotation method is a special option for steel tower construction in fabricated bridge. The tall tower is prefabricated on the ground and then pulled to its designed position using steel wires. Traditional vertical rotation method always uses a taller temporary structure to provide an upward pull force to lift the rotation member; however, the temporary structure would spend much time, cost, and work high above the ground. For instance, the Jinwu Bridge tower’s weight was so heavy that the ordinary rotating method was not feasible. Therefore, a relay traction system with two auxiliary struts was employed to rotate the tower. The chief strut was first rotated to an inclined angle of 60° by an assistant strut to decrease the lateral component force of tension. Then, the tower was pulled from horizontal to vertical by the chief strut. Furthermore, a numerical model was established to analyze the mechanical behavior of the inner force, stress, and deformation of the chief strut, assistant strut, and tower. The study identified critical conditions such as the reverse of axial force for the assistant strut, intervention of back cables, and release of cable tension. The relay traction system effectively reduced initial pulling stress, spending less cost and time. Besides, the analysis method can be an innovate reference for other vertical rotating projects.

“…It has a number of advantages, such as greater torsional rigidity, durability, construction and maintenance, aesthetic as well as economic advantages (Su, Yang, & Wu, 2012;Zhou, Jiang, & Yu, 2013;Fatemi, Ali, & Sheikh, 2016;Soto, Caldentey, Peiretti, & Benítez, 2020). In addition, steelconcrete composite box girder bridges are a structural system that offers economic, constructive and lower environmental impact advantages, since it optimizes the use of steel and concrete materials, allocating tensile stresses to steel and compressive stresses to concrete (Nicoletti, Rossi, Souza, & Martins, 2021a;2021b).…”

“…Acta Scientiarum. Technology, v. 46, e64764, 2024 In the context of steel-concrete composite bridges, the effective width is a widely studied topic (Dezi, Gara, & Leoni, 2003;Amadio, Fedrigo, Fragiacomo, & Macorini, 2004;Chiewanichakorn, Aref, Chen, & Ahn, 2004;Macorini, Fragiacomo, Amadio, & Izzuddin, 2006;Gara, Leoni, & Dezi, 2009;Gara, Ranz i, & Leoni, 2011;Salama & Nassif, 2011;Wang & Nie, 2015;Zhu, Nie, Li, & Ji, 2015a;Galuppi & Royer -Carfagni, 2016;Yuan, Deng, Yang, Weijian, & Zhenggeng, 2016a;Reginato, Tamayo, & Morsch, 2018;Lasheen, Shaat, & Khalil, 2018;Silva, & Dias, 2018;Nicoletti et al, 2021a;2021b).

Steel-concrete composite girders have non-uniform stress distribution on the slab, presenting maximum stresses next to the webs of the girder. This phenomenon is known as shear lag effect. To understand this effect, there is the effective width concept, in which only a portion of the slab width is considered effective in contributing to the composite element’s resistant capacity. However, in the technical standards, there is no recommendation for calculating the effective width in steel-concrete composite box girder bridges. In view of this situation, the purpose of this paper is to carry out a systematic review on effective width and/or the shear lag effect in steel-concrete composite bridges, in order to raise the main existing recommendations and compare them. Through a bibliometric scan with carefully chosen keywords, it was found that of all research on shear lag or effective width in steel-concrete composite structures, only 31.19 are on bridges and 14.97% are on bridges with box girders. Among the papers, those that have a method for calculating the effective width of steel-concrete composite girder bridges have been compared quantitatively and qualitatively with the procedures of AASHTO and EN 1994-2-2. In these procedures were also identified that the, for the boundary conditions of the present paper, the parameters that most influencing the effective width are, in that order, the span length, the distance between girders, the concrete slab height, the longitudinal position and the type of load.
