“…In later years, the spline finite strip method was extended to right box girder bridges by Cheung and Fan [98]. Arizumi et al [99] studied the distortional and slip behavior of simply supported curved composite box girder bridges using the finite strip method. The results from the proposed finite-strip method compared favorably to those obtained from curved beam theory, distortional theory, and static tests.…”

“…The comparison showed close agreement between the shapes but not the magnitude of the stress plots. Arizumi et al [99] tested three models of curved composite box girders. The measurements obtained from the test were compared to the finite strip method and Dabrowski's [16,17,18] distortion theory.…”

: Box girders are now prominently used in freeway and bridge systems due to their structural efficiency, better stability, serviceability, economy of construction and pleasing aesthetics They are most suited for bridges curved in plan because of its high torsional rigidity. A study of box girder curved in plan with trapezoidal cross section has been carried out in the present investigation. The analysis is carried under the dead load, super imposed dead load, live load of IRC Class A tracked vehicle and prestressed load .This paper focus on the parametric study of box girders with different radius of curvature by keeping the span, cross sectional shape and material properties constant . The parametric investigations performed on curved box girders helps to evaluate the effects of change in radius of curvature on the behaviour of the box girders. This study would enable bridge engineers to better understand the behaviour of curved box girders and the results presented will be a valuable guidance to them.

“…Vlasov [ 2 ] established governing differential equations for curved beams based on the three major equations of mechanics, which laid the foundation for subsequent theoretical research. Later, some Japanese scholars [ 3 , 4 , 5 ] conducted related research on one-dimensional theoretical models for curved box beams and proposed relevant design proposals for the behavior of shear lag and distortion. At present, the main idea of the research on one-dimensional beam models of curved beams is to introduce functions with relevant degrees of freedom (DOFs) on the basis of Vlasov’s curved beam theoretical model to enable corresponding analyses.…”

Curved steel–concrete composite box beams are widely used in urban overpasses and ramp bridges. In contrast to straight composite beams, curved composite box beams exhibit complex mechanical behavior with bending–torsion coupling, including constrained torsion, distortion, and interfacial biaxial slip. The shear-lag effect and curvature variation in the radial direction should be taken into account when the beam is sufficiently wide. Additionally, long-term deflection has been observed in curved composite box beams due to the shrinkage and creep effects of the concrete slab. In this paper, an equilibrium equation for a theoretical model of curved composite box beams is proposed according to the virtual work principle. The finite element method is adopted to obtain the element stiffness matrix and nodal load matrix. The age-adjusted effective modulus method is introduced to address the concrete creep effects. This 26-DOF finite beam element model is able to simulate the constrained torsion, distortion, interfacial biaxial slip, shear lag, and time-dependent effects of curved composite box beams and account for curvature variation in the radial direction. An elaborate finite element model of a typical curved composite box beam is established. The correctness and applicability of the proposed finite beam element model is verified by comparing the results from the proposed beam element model to those from the elaborate finite element model. The proposed beam element model is used to analyze the long-term behavior of curved composite box beams. The analysis shows that significant changes in the displacement, stress and shear-lag coefficient occur in the curved composite beams within the first year of loading, after which the variation tendency becomes gradual. Moreover, increases in the central angle and shear connection stiffness both reduce the change rates of displacement and stress with respect to time.
