beam or "girder" bridge is the simplest and most inexpensive kind of bridge. According to Craig Finley of Finley/McNary Engineering, "they're basically the vanillas of the bridge world." In its most basic form, a beam bridge consists of a horizontal beam that is supported at each end by piers.
My hypothesis was that the arch bridge would be the strongest. The experiment involved building and testing the strength three bridge types (arch, beam, and truss) by increasing the amount of weight on each bridge while measuring how much each deflected (bent), and at what point the bridges failed (broke).
Steel and concrete are the most popular choices for modern bridge construction. Other materials include wood, iron (a different type of steel), plastic and stone. Before the availability of steel and concrete, most bridges were made of wood, rope and/or stone.
Build a Bridge. Many people lift by bending over at the waist and leaving their upper body hanging like a “one-sided bridge”. This places all the demands of the lift onto the lower back and increases the risk of injury. This can be avoided by “building a bridge” to support the weight of the upper body.
For designing safe bridge structures, the engineering design process includes the following steps: 1) developing a complete understanding of the problem, 2) determining potential bridge loads, 3) combining these loads to determine the highest potential load, and 4) computing mathematical relationships to determine the ...
Cofferdam technique is used in this case. In this method, a wall enclosing an area is build inside the water and water is continuously pumped out from the area. After that, foundation of the bridge(the pillars) is constructed inside the cofferdam. As the construction place is sea or river itself.
The triangle is the strongest to as it holds it shape and has a base which is very strong a also has a strong support. The triangle is common in all sorts of building supports and trusses. The overall shape of many bridges is in the shape of a catenary curve.
The arch bridge can hold the most weight of the three, the deck truss bridge can hold an average amount of weight, and the beam bridge could hold the least amount of weight. This experiment tested the arch, deck truss, and beam bridges to see which could hold the heaviest amount of weight.
Strength. An arch bridge is stronger than a beam bridge, simply because the beam has a weak point in the center where there is no vertical support while arches press the weight outward toward the support.
The Howe truss had an average load-to-mass ratio of 512.61 and deflected 13.23 mm on average. The Pratt truss had an average load-to-mass ratio of 528.93 and deflected 9.53 mm on average. The Pratt truss deflected the least and had the highest load-to-mass ratio.
The idea of the K truss is to break up the vertical members into smaller sections. This is because the vertical members are in compression. The shorter a member is, the more in can resist buckling from compression.
Suspension bridges are strong because the force on the bridge gets spread out. The weight of the cars or trains or horses, whatever's traveling across it, pulls on the cables, creating tension. Those cables then pull down on the towers and also pull on the anchors on either end of the bridge, to hold up the deck.
The arch-style bridge is one of the most ancient, used in the aqueducts of Rome and in designs from the present day. Building these bridges has become more efficient with modern technology, but the original design is still so commonly relied on because of its natural strength. However, it must be built from both sides.
Truss bridges are extremely effective because they have a high strength to weight ratio. In this experiment we have tested which type of truss bridge is the strongest, yet uses the least amount of material. Two of the most used truss bridges are of the Pratt and Howe design.
