With the rapid development of country’s economy, a large number heavy vehicles are being used due to expansion transportation demand and increased costs. For old concrete truss-arch bridges built in last century, may hardly meet modern traffic volume. respect poor condition, it takes more time resources evaluate technical status by field load tests, there some safety risks. A finite element met...

The present aim of this study is to investigate the effect of different parameters influencing pounding in highway bridges. Pounding is the result of a collision between two parts of the deck and/or the deck and abutments at the separation distance during the earthquake.  In the present study, the period ratio of the adjacent frames, ground motion spatial variation, and soil-structure interacti...

This paper proposes a new methodology to simulate wind fields that are non-orthogonal the structure and traffic direction, it presents first wind–vehicle–bridge interaction (W-VBI) analysis framework account for skew effects on driving safety. The three-directional generated match well target frequency content correlation properties along deck. W-VBI is applied study of vehicles crossing long b...

the vibration of cable-stayed bridges subjected to the passage of high-speed trains is studied in this article. the moving train includes a number of wagons, each of which is modeled as a four-axle system possessing 48 degrees of freedom. the car model is nonlinear and three-dimensional and includes nonlinear springs and dampers of primary and secondary suspensions, dry friction between differe...

In network environments, the entities that connect to or interact with each other may know very little about each other or without prior knowledge at the beginning of an interaction. Therefore, in many cases, before a serious interaction begins, trust must be established between the interactive entities. During trust establishment, an entity may require that the other entity provide some inform...

This paper presents a novel approach to the reduction of short-span bridge dynamic responses to heavy vehicle crossing events. The reductions are achieved through adjustment of the vehicle suspension damping coefficient just before the crossing. Given pre-calculations of the response of a vehicle-bridge system to a set of ‘unit’ road disturbances, it is shown that a single optimum damping coeff...

When depth of flow past a river bridge exceeds opening under the bridge, the flow under the bridge becomes pressurized. The water is directed downward and under the bridge deck, causing increase in velocity and shear stress on the bed thereby increasing bed scour. This is termed as Pressure Flow Scour. The present study investigates the phenomenon of pressure flow scour resulting from a submerg...
