Bridge Structures and The Use of Geometry in Their Design What is a bridge? A bridge is a structure providing continuous passage over a body of water‚ roadway‚ or valley. Every bridge looks different from the another. Their bridge structure is different. There are nine types of main bridges. Bridge engineers use a lot of geometry to help them design the different bridges. Without geometry‚ the bridges would not be safe. Bridges have been around for a long time. The earliest bridges

Bridge Failure Studies and Safety Engineering 2.1 HISTORY OF DISASTERS AND SAFETY MANAGEMENT 2.1.1 Unexpected Material Deterioration and Failure Engineering is usually about avoiding failures and investigating why failures occur and ways to fix the problem. There is a need to understand the conditions giving rise to past failures and ways to avoid such failures so that loss of life can be minimized. Historical events and selected case stud-ies demonstrate the causes of

1970 Apollo 13 took flight to the moon. Fred Haise‚ Jack Swigert‚ and Jim Lovell were the three men who had the privilege to be the three astronauts that would man this flight to the moon. Days before the mission‚ the original main pilot‚ Ken Mattingly was exposed to the measles and was believed to have fallen ill‚ so back up pilot Jim Lovell was called in to replace him. Now that the crew had been assembled it was time for launch. Before the three men had taken on the challenge of Apollo 13 they

When people in the United States today hear the term "London Bridge‚" they are most likely to think of one of the most peculiar sights anywhere within the United States that of the London Bridge in Lake Havasu City‚ Arizona. Surrounded by faked-up Tudor buildings and busloads of tourists‚ the large bridge is dwarfed by the majesty of the desert Southwest. The entire enterprise stands as a monument to a deep human appreciation for irony‚ for what else could explain the immense cost and energy that

Suspension Of all the bridge types in use today‚ the suspension bridge allows for the longest spans. At first glance the suspension and cable-stayed bridges may look similar‚ but they are quite different. Though suspension bridges are leading long span technology today‚ they are in fact a very old form of bridge. Some primitive examples of suspension bridges use vines and ropes for cables. Typical Span Lengths 70m - 1‚000m+ World’s Longest Akashi Kaikyo Bridge‚ Japan Total Length 3‚911m

“BROOKLYN BRIDGE” The Brooklyn Bridge’s construction is one of the great achievements in United States history and helped pave the way for New York City’s rapid expansion in the 19th and 20th centuries. It was an undertaking that required extraordinary effort‚ sacrifice and ingenuity by its designers as well as its builders to complete. Its completion was a feat of engineering that was unmatched in its time: it was the longest suspension bridge – the first to use steel-wire – and dominated the New

For instance‚ the Baltimore‚ Pennsylvania‚ and the Parker are all based off the Pratt.

The first shows the load being applied across the entire top of the bridge. The second shows a localized load in the center of the bridge. In both
