“…The researcher analyzed the reaction forces of the bridge. Samaan et al (2007) simulated a vehicle–bridge system using a pair of concentrated forces moving along a finite element curved bridge and studied the effects of bridge configurations, loading positions, vehicle speed, and vehicle mass on the impact factors (IMs) Xia et al (2008). researched the lateral dynamic interaction between a three-dimensional train model and a curved railway bridge and compared the numerical results with field experiments Dimitrakopoulos and Zeng (2015).…”

Considering the nonlinear property of suspension damping and tire stiffness, a full-vehicle model is built for a heavy-duty truck. A modified preview driver model with nonlinear time delay is inserted into the vehicle model to compute the suitable steering angle of the front wheel and to make the vehicle follow the required route. Next, the finite element model of a five-span continuous curved highway bridge is established, and the bridge's inherent frequencies and modes are obtained. The curved bridge and the vehicle are coupled by three-directional tire forces, and a three-directional driver-vehicle-bridge interaction model is presented. The presented vehicle model and bridge model are verified by comparing with the published works. The dynamic impact factors of vertical, lateral, and torsional displacements of the bridge are calculated when a vehicle is traversing through the bridge, and the impact factors' distributions along the bridge are analyzed. The effects of vehicle driving conditions on impact factors are also researched. It is found that the impact factor calculated from the present specification for a straight bridge is smaller than that from the three-directional drivervehicle-bridge interaction model, and the vertical and torsional impact effects at the third span midpoint are greater than the lateral impact effect.

“…The effect of the mass of the vehicle on the dynamic response of the bridges was also investigated. A part of the study aimed to design curved, continuous, composite multiple-box-girder bridges more reliably and economically (Samaan et al, 2007b). A method for determining the dynamic impact factors for horizontally curved, composite, single or multicell box-girder bridges under AASHTO truck loading was studied by Sennah et al (2004).…”

2This paper studies the non-linear dynamic behaviour of the steel-concrete composite, curved box beam by using the finite-element method. A three-dimensional finite-element model has been developed to obtain natural frequencies and mode shapes. A parametric study was also conducted to evaluate dynamic behaviour of composite, curved box beams. The results indicate that the frequencies of the composite box beam decreases slightly with an increase in the stud spacing (pitch of shear connector), but the frequencies and mode shapes change significantly when the stud spacing exceeds the double stud spacing (two times the pitch of the full shear connection). This tendency is particularly obvious in the extend mode shapes.

“…Julian, Hayashikawa and Obata (2006) studied the seismic performance of isolated curved steel viaducts equipped with deck unseating prevention cable restrainers, resealing that special attention should be paid to the non-linear bridge dynamic response in order to avoid the failure of restrainers. Samaan, Kennedy and Sennah (2007a, b) studied the results from a parametric study on the impact factors for 180 curved continuous composite multiple-box girder bridges, and put forward expressions for the impact factors for tangential flexural stresses, deflection, shear forces and reactions under AASHTO truck loading. Empirical expressions were deduced from results generated from experiments and by using finite element methods to evaluate the fundamental frequency for such bridges.…”
