Railroads, Truss Bridges and the Rise of the Civil Engineer
The huge growth of the railroads during the nineteenth century was the direct result of herculean efforts on the part of civil engineers. Likewise, the development of the civil engineering...
James B. Eads and His St. Louis Bridge
Eads Bridge at St. Louis, a century old engineering achievement, was designed, promoted, and built by an intensely dedicated and self-educated man, James B. Eads. This structure was an...
Philadelphia Bridge Sparked Growth of Prestressed Concrete in the U.S.
Prestressing has been used for centuries. For instance, iron bands were heat-shrunk over built-up wooden wheels to increase their resistance to damage. In 1888, a man named Jackson from...
Why Do Bridges Fail�
From the study of 143 bridge failures that occurred throughout the world from 1847 to 1975, it is found that there are nine categories of failure. The most frequent of these is failure...

New Orleans Grows on Deep Piles
In the New Orleans area, tall buildings must be supported by piles extending at least into the preconsolidated clays at -150-ft (-46-m) or so. Settlement is much too severe and uneven...
Inverted Filter Stabilizes Soil, Stops Erosion
The inverted filter concept was invented by Karl Terzaghi to prevent dams from failing by water piping through the foundation. Laboratory and field testing have refined the necessary specifications...
