On the Dynamic Response of Bridges by Oscillating Vehicles on Rough Surfaces
The spectral theory is applied to the response of bridges under a Poissonian stream of vehicles moving with constant speed over the bridge. The vehicles are modeled as oscillators with...

Approximate Reliability Analysis of Highway Bridges Under the Action of Random Vehicles?In Relation to an Interchange Bridge of China
In relation to an interchange curved bridge of China, a simple method by FSE for analysis of stochastic vibration has been proposed. The random vibration characteristics of bridge structures...

Reliability of a Suspension Bridge Under Traffic Flow
The problem of reliability of a single-span spatial suspension bridge under random highway traffic is considered. The displacements of the bridge are described by coupled, non-linear,...

Mode Truncation Effects on Flexible Space Structures
This paper deals with the problem of active vibration control of flexible space structures. The main difficulty associated with this problem is that the structure has infinite vibration...

A Supertrain Solution?
A high speed steel wheel rail line has been highly successful in France, where ridership has been very high. Financial backers were paid back in seven years, half the projected payback...

Unlocking Arena Gridlock
The Charlotte Coliseum features a $22 million reversible lane system, which provides easier access to and from 8,000 parking spaces. To improve access to the arena, a 3.6 mi road extension...

Pilot Bore Pays Off
The primary purpose of tunneling through Cumberland Mountain is to ease the 18,000 vehicle per day traffic through the rugged terrain that was a major transportation route when Daniel...

Valve Control to Avoid Column Separation in a Pipe
Maximum pressures in a pipeline can be reduced significantly by closing the valve in an optimal manner. Such an optimal valve closure policy may result in some situations in minimum pressures...

Less Bang for the Buck
Blasting rock is practical on job sites with ample space, but on construction sites in urbans or developed settings, contractors are shying away from blasting for several reasons. Noise...
