Question:

Answers:Less material, thus less weight of bridge to support, less blockage of view, piecewise assembly may permit making the bridge where large bridge beams might not make it in although truss bridge sections are often assembled and lifted into place as one large section. Higher maintenance of all the joints and fittings, more calculations to determine that it will take the maximum load.

Question:i want to know the advantage of arch bridges

Answers:The advantage is it produces very strong bridges. The disadvantage is that you can't use this technology for long bridges (because the arc gets too high in the middle). ~

Question:i need it for school if you could tell me advantages and disadvantages of other bridges that would be totally apprieciated

Answers:Can you remember a time when you crossed a bridge? Did you wonder how it could hold so much weight or think about how it was built? Or did you just take the bridge for granted? Well, bridges are a crucial part of our transportation system and a part of life. Bridges save you from taking long alternative routes, thus saving you time, money, and gas. Bridges, from the simplest and most primitive logs, to the modern suspension bridges that can span more than 1,200 meters, have been helping us cross over rivers, gorges, bays, and other obstacles for centuries by handling loads through dissipation and transference. Truss bridges are one of the simplest bridges and there are many different designs for them that vary in their placement of members and how they distribute force. It is important to know which type of truss bridge has the best strength-to-weight ratio because it can help save money yet still support its burden. Have you ever went over or on a bridge and wondered how it worked and supported all the weight that was on it? Bridges work because of how they handle two different forces, compression and tension. All types of bridges have to deal with these forces without buckling or snapping. The most efficient way to cope with these forces is to dissipate them or transfer them. An arch bridge is a good example of dissipation because dissipates force outward of the arch. A suspension bridge is a good example of transference because their cables transfer force to the towers, which in turn dissipate the force into the ground. Bridges have been around for ages. The first bridges were probably just logs positioned over a stream. The Roman arch bridge was the first real development in the history of bridges. Amazingly, there are Roman bridges that still stand today, even though some are more than 2000 years old. The first truss bridges were developed in the 1500 s. In the 1700 s, iron began to be used to make bridges, a big improvement over wood. Suspension bridges were built in the 1800 s allowing people to cross greater distances. The first concrete bridge was built in 1869, and eventually bridge builders began using reinforced concrete, giving bridges greater strength. Truss bridges are one of the simplest bridge types. They use a relatively small amount of material to support a load compared to other kinds of bridges. There are many different designs for truss bridges, each unique in how it dissipates its load to its members. Truss bridges are more suited for covering smaller distances, but they can be made longer by adding supports along the span. There are many different styles of truss bridges. One of the most common types is the Warren truss. It is characterized by a zigzag design or triangles without any vertical supports, though vertical supports are sometimes added for longer distances. It is best for spanning distances of 50-100 meters. Another common type of bridge is the Pratt truss. It is identified by its diagonal members that slant down to the center. This design is reliable but not very cost-effective.

Question:

Answers:Advantages: Lets you get from one side of a river to the other without getting wet. Lets small boats go underneath. Disadvantages: Take time and effort to build. Can't move them like you can a swing bridge.
