Open image in new window Figure 3 Finite element model of bridge tower.
In this way, the prediction capability of the linear equivalent model of bridges supported on LRB isolators is improved.
Since accelerometers are the most practically used sensors, the simulated acceleration time history has been used to illustrate the approach with idealized model of bridge and vehicle.
These expressions were derived based on the model of bridge with rigid deck and pier condition subjected to stationary white-noise excitation.
On the basis of predecessors' research, this paper considered the PID active suspension control and used the delicate FEM model of bridge and at-ground structure based on co-simulation of SIMPACK and ANSYS.
Assumptions/considerations are proposed for the present study in the following sub points: Open image in new window Fig. 2 Simplified model of bridge with MTMFD under multi-axle vehicle 1. Stiffness of each TMFD unit is the same.
Firstly, based on a large scale section model of bridge in the wind tunnel, the aerodynamic coefficients of two types of high-sided road vehicles, located on bridge deck, are obtained as different wind barriers installed on the bridge.
Smith et al. (1995, 1997; Smith and Hashemi 2006) used AHP method to characterize the bridge material decision process of highway officials in selected states and developed a behavioral model of bridge material selection for several states and for several levels of decision makers.
His show at the Gagosian, which runs through Feb. 28, juxtaposes large stainless-steel models of bridges with bullets cast in 24-karat gold, archetypes of patient construction and instant destruction.
Whether pushing himself to the extremes of pain and discomfort, creating scale models of bridges from Meccano, building fuel-efficient vehicles or toy-car cities, he attempted to transcend physical limits and explore the psychological impact of actions and objects in the world.
