They require efficient design to really work. With this in mind, installation and maintenance of these bridges might be unmanageable for certain communities.Ĥ. While the extra materials provide them with a lot of strength, they would cost a lot of money for the labor to keep them functional. As many people realized, this bridge may not be the most cost-effective option for their communities.īecause of the amount of materials they use, these types of bridges require a lot of upkeep. Maintaining a truss bridge can be more complicated and expensive, thus it can be a huge drawback for a community that is having a tight maintenance budget. And even if this type of structure is strong, having the capability to support a lot of force, it is not seen to be built anymore these days due to the high costs that come with it. Building a truss bridge can be costly, and its upkeep requires time and money. ![]() While it is said that these bridges’ design efficiently uses materials, it does use a lot of them. These bridges need additional amount of space when compared to other types, which means that certain locations might need adjustment of existing structures in order to accommodate these bridges. Though it uses more of the materials and requires many support rods and poles, these components can be made from different materials, while other types of bridges usually depend only on metal. Because of its design, it makes good use of limited construction materials to achieve strength that far outweighs its cost. As it has a deck tress, it allows certain transportation options, such as a rail, to be placed straight across it, offering a stable point for crossing any span.Ī truss bridge can be built from metal or wood. They allow placement of roadways on the structure itself.Ī truss bridge is the only type of bridge that allows a roadbed to be placed on the structure itself. This is definitely a huge advantage when it comes to using these bridges.ĥ. These types of bridges can be built quickly in places where many other types cannot, linking areas that other types will not work in. ![]() They can be built under extreme conditions. In some situations, you will see truss bridges built conveniently to connect over railways and between mountains.Ĥ. Even in areas where, initially, it might be impossible to build such a structure, truss bridges can allow for a strong span and can still effectively hold heavy amounts of traffic. Aside from this, it does not take much effort to create a suitable environment for these bridges to be properly installed. One of the primary reasons that truss bridges have been the preferred structures over other types is their versatility to be constructed in places where construction could be difficult, such as locations needing long span of areas like deep trenches. They can be constructed virtually anywhere. These structures tend to hold up well for a long time, serving a lot of communities very well.ģ. While truss bridges are among the oldest types of bridges still used in the world today, they are still considered as among those having the best state-of-the-art designs. ![]() As they use small timbers or beams of metal, the trusses would be light, but are strong enough to handle loads thanks to the ridged triangles that are an integral component of their designs. Most of the time, these bridges effectively use materials needed for their construction, making them very economical to build, while not compromising on their grounds. To build or own opinion about this matter, let us take a look at their pros and cons. However, like other major structures, truss bridges have been a subject of debates that discuss whether they are appropriate to construct or not. Their simple styles have been analyzed since the 19th century. Their linked elements that are normally straight are thought to be designed to be stressed from tension, compression or, most of the time, both aspects to handle to lively loads-in fact, these bridges have a unique ability to take compression and tension more than other bridge designs. They are among the oldest types of bridges that are found all over the world and are still regarded as state-of-the-art technology. There are various types of bridge designs, with each having its own set of strengths and weaknesses, and among these designs having a superstructure with link elements creating triangular units are known as truss bridges.
