DYNAMIC RESPONSE CHARACTERISTICS OF PLATE GIRDER BRIDGE SUBJECT TO MOVING MOTOR VEHICLE

Oscillator Experiment of Simple Girder Bridge coupled with Vehicle

This study presents experimental investigations on dynamic characteristics of bridges coupled with vehicles in order to clarify the vehicle-bridge interaction under earthquakes. Oscillator experiment is carried out at a one-box girder bridge coupled with a vehicle. Both acceleration responses of the bridge and those of the vehicle are measured in horizontal and vertical directions. The dynamic ...

Economical Steel Plate Girder Bridges

As a service to the bridge design profession, Bethlehem Steel has conducted hundreds of studies of steel plate girder bridges using its Preliminary Bridge Girder Optimization Program. The program is unique because it optimizes plate girder designs on the basis of least cost, not least weight. An evaluation of many study results leads to a number of guidelines which are offered in this paper. Wh...

Dynamic Behavior Analysis of a Geometrically Nonlinear Plate Subjected to a Moving Load

In this paper, the nonlinear dynamical behavior of an isotropic rectangular plate, simply supported on all edges under influence of a moving mass and as well as an equivalent concentrated force is studied. The governing nonlinear coupled PDEs of motion are derived by energy method using Hamilton’s principle based on the large deflection theory in conjuncture with the von-Karman strain-displacem...

An Investigation Into the Vehicle-Curved Bridge Dynamic Interaction

Dynamic Response of an Axially Moving Viscoelastic Timoshenko Beam

In this paper, the dynamic response of an axially moving viscoelastic beam with simple supports is calculated analytically based on Timoshenko theory. The beam material property is separated to shear and bulk effects. It is assumed that the beam is incompressible in bulk and viscoelastic in shear, which obeys the standard linear model with the material time derivative. The axial speed is charac...
