By George C. Lee, Ernest Sternberg

A multidisciplinary and obtainable advent to humanity’s favourite constitution: the bridge.

Whether you're a scholar contemplating a profession in civil engineering and transportation making plans, a public respectable drawn to the way forward for infrastructure, or anyone who easily cares approximately bridges, this publication bargains an obtainable and illustrated advent to the main cherished characteristic of our equipped setting. know about engineering fundamentals: the forces that bridges needs to face up to to stick aloft and the rules through which engineers come to a decision which kinds of bridges make feel at which internet sites. learn how engineers shield bridges from their maximum threats—the earthquakes, floods, and different dangers which could reason catastrophic damage.

relocating from engineering to making plans, find out how we choose even if a bridge is worthy development within the first position, find out about arguable positive aspects of cost-benefit research, and in regards to the transportation versions wherein planners forecast bridge results on site visitors styles. examine a occasionally intractable challenge: why a venture frequently creeps alongside for a decade or extra to get from preliminary reports to the day the ribbon is reduce, present process great rate escalations. additionally discover the environmental effect of bridges, and the which means of a “sustainable bridge,” and even if bridges may once more be equipped, like historic Roman ones, to final 1000 years.

“Authoritative, complete, and enjoyable to learn, this e-book is for everybody attracted to bridges, from the lay reader to the techie who likes to determine how issues paintings. It will also function a good significant other to starting layout scholars in structure and engineering, and it may be on the shelf of civil engineers, architects, and contractors, too.” — Robert E. Paaswell, urban collage of latest York

“This paintings might help informed yet nonspecialist choice makers to understand the complexity of bridge layout, building, and upkeep in making judgements that effect bridges.” — Niraj Verma, Virginia Commonwealth collage

Example text

It is worth taking a moment to note this specialized use of the word web, which has nothing to do with our usual image of it. An alternative to the I-beam is the box beam, which has the cross-sectional shape of, well, a box. 1). Its advantage is that it has better resistance to torsion forces than the I-beam does. Its disadvantage is that it is more costly to fabricate. Though the interesting bridges one sees are composed of wires, cables, beams, and columns, we begin our discussion of bridge types with the most modest kinds of bridges, the culvert and slab.

Its disadvantage is that it is more costly to fabricate. Though the interesting bridges one sees are composed of wires, cables, beams, and columns, we begin our discussion of bridge types with the most modest kinds of bridges, the culvert and slab. CULVERT AND SLAB BRIDGES Though rarely discussed, culvert and slab bridges are ubiquitous on American roads. The culvert may be a concrete or rock structure with earth covering, above which a road runs. Or it may just be a large pipe crossing under the road.

First, as we move from the wall toward the free end, each vertical layer of cubes has slid slightly downward as compared to the neighbor closer to the wall. In short, each has undergone shear strain. Second, the top layer of cubes has been elongated, causing tensile strain; it is greatest right next to the wall. Third, the bottom layer of cubes has shortened, causing compressive strain; it, too, is greatest right next to the wall. 10). The critical payoff for the structural designer is obvious: the longer the cantilever (everything else being equal), the greater the downward dip, and the greater the strain (compressive and tensile) next to the wall.
