“…According to the test setup, the model was restrained with hinge and roller supports at the ends and loaded with a series of concentrated loads applied over 500 × 200 mm patch areas [36] to mimic two sideby-side HS-20 trucks with a modified axle spacing. The proposed FE model was analyzed using static analysis with the Newton-Raphson nonlinear solution algorithm.…”

To assess a precast concrete vibrating table, a system mechanics model was established by using the transverse vibration theory of thin plates. The model was then simplified as a stiffened plate structure according to the structural characteristics of a vibration platen. Specifically, the vibration mode functions of the vibration platen were established by utilizing a two-dimensional beam function method in which the maximum kinetic energy and maximum strain energy of the vibration platen were derived. Additionally, the Rayleigh-Ritz method based on the displacement variation principle was utilized to analyze the natural frequency and mode shapes of the vibration platen. A comparison between the theoretical calculation results and the finite element simulation results indicated that the established vibration mode functions can appropriately reflect the mechanical behavior of the vibration platen, which verified the correctness of the analysis method for the inherent characteristic of the vibration platen and provided a preliminarily theoretical basis for the performance improvement of a precast concrete vibrating table.

“…[3] provided a finite element model to investigate the effects of girder spacing, span length, overhang distance and skew angle on the shear live-loud distribution factor. Harris and Gheitasi [4] presented an analytical approach for determining lateral load distribution characteristics of beam-slab type bridges, using classical plate theory. A modified method was developed [5] based on the rigid-jointed girder method considering the different main girder stiffnesses and the space between the original bridge and the widened bridges.…”

Abstract. This paper presents a modified rigid cross beam method to study the lateral distribution of multi-I beam composite curved bridge with slip effect. First, the effective stiffness expression of single composite curved beam with slip effect were established and calculated by the FEM. Secondly, the lateral load distribution of multi-I beam composite curved bridge is obtained by substituting the effective stiffness of the main composite curved beam into the rigid cross beam method. Finally, The FEM numerical examples show that this method can accurately describe the load distribution characteristics of multi-I beam composite curved bridge with slip effect.
