Bridge Engineering

No one wants to make something twice. That’s why it’s so important to build it to perfection the first time, especially if it’s something time-consuming and expensive such as a bridge. With extensive experience in bridge engineering, bridge construction can be effortless and efficient.

At U.S. Bridge, we’ve been engineering and building bridges for over 80 years. Here’s how our bridge engineering process leads to seamless bridge construction.

The Bridge Engineering Process

Understanding the Problem

There are several different reasons to build a bridge. It could be to connect communities or provide a secure commerce route for heavy trucks. Regardless, the first step for the bridge design team is to understand why the bridge is being built. What problem is it meant to solve?

Once our team of engineers understands this, then they can move forward in designing a bridge that will properly address the reason for the bridge.

Understanding the problem also allows engineers to answer other questions such as where and how. It’s the first step to designing the final product.

Determining the Scope

After knowing more about the problem, our engineers create and compare different solutions to the problem. This includes analyzing what design would work best for the bridge and the pros and cons of each option. Then they also consider other factors like the weight of the materials and how the environment would affect the bridge.

We establish elements like the structural capacity, environmental impact, and constructibility of the bridge. In the final analysis, all of these factors and more are carefully considered to determine the scope of the bridge construction project.

The Actual Design Process

Once the scope of the project has been determined, then our engineers are able to begin the design process. Theories of solutions materialize as we calculate the details on elevation, span lengths, deck widths, vertical clearances, and bridge structure among other logistics.

In addition, we also create virtual models to enable our customers to visualize their project.

This is also the part where we create an initial budget analysis for our clients. These calculations are vital to the bridge design process. Budgets are how we ensure the project is ideal for the bridge owner’s needs before proceeding to the construction phase.

The Bridge Construction Process

Our various manufacturing options provide a solution for various projects and budgets. From timber bridges to prefabricated steel, we design, manufacture, and build them all. Following the decisions finalized during the design phase, we begin the construction process. Our bridge supplies are shipped worldwide and our team is present during construction to guarantee its execution.

With more than 250,000 sq ft of engineering and fabricating facilities including dedicated truss, painting, and post and tube centers, located on a 6-acre campus, we provide the highest level of quality bridge available.

Throughout the entire process, we work directly with our clients and communicate with all members of the project for an effortless process.

Truss Bridge

There are several timeless designs that have been used in bridge building for decades. However, there are few more iconic than the truss bridge. In the 1800s, America was the leader in truss bridge design, though older constructions used wood. The design is vintage Americana, but it’s become modernized.

Today, truss bridges are used as an effective bridge construction option. Although one thing has changed: steel is the primary component in new truss constructions. U.S. Bridge is a leader in building modern truss bridges that will last for decades to come.

Let’s discuss why we use steel truss bridge design for many of our new constructions.

Advantages of Steel Truss Bridges

  1. Strong load-bearing capacity
  2. Effective use of materials
  3. Affordable to construct
  4. Versatile and adaptable design
  5. Professional bridge engineering

Steel Truss Bridge

First, What is a Truss Bridge?

Truss bridges are formed with a structure of connected elements that form triangular structures to make up the bridge. Trusses are the triangles that connect to the top and bottom cord and two end posts.

The trusses make up reinforcement for the bridge that even the load-bearing across the structure. Furthermore, the truss dissipates the load through the structure so the middle of the beam experiences less compression and tension. As you will see later, there are several variations of the truss, but it starts with a top and bottom cord and a series of trusses.

1. Strong Load-Bearing Capacity

Even the earliest wood truss bridges were built to distribute weight evenly. With this intention in mind, bridges could be built for larger loads. Overall, this makes this bridge design a very strong and dependable option. With steel construction, truss bridges can take on the traffic of today.

2. Effective Use of Materials

What makes truss bridges relevant more today than ever is their effective use of materials. Keep in mind, less materials means easier construction and less money spent. Already, our bridge construction uses recycled steel that is lightweight and has been certified for Bridge Fabrication — Advanced (Major) by the AISC.

In fact, each piece is constructed with a definite purpose for truss bridge construction. This way, the construction and use of each steel piece are perfect for the bridge.

3. Affordable To Construct

Because of the simplicity of truss bridge designs, they are often a great fit for accelerated bridge construction. In order to improve construction time, each steel piece can be quickly pieced together.

If considering the full cost of material and labor, truss bridges save builders thousands of dollars. Not to mention the long-term savings from building a long-lasting, durable bridge from U.S. Bridge.

4. Versatile and Adaptable Design

While truss bridges are great for short spans, what makes them versatile is their ability to go long distances and still support large loads. With the polygonal design of the truss, it’s possible to cover long distances. Even at U.S. Bridge, we have several options to fit the bridge construction you’re looking for.

In particular, truss bridges can be needed in areas with extreme weather. Despite the harsh weather, with great structural engineering, our truss bridges are prepared to last even the worst storms for decades to come. When it comes to crossing a treacherous area, truss bridges can be built to keep communities connected.

5. Professional Bridge Engineering

While a truss bridge may seem simple, they are actually quite intricate and require complex engineering and design. Because the weight must be distributed away from the center beam, each truss must be optimally engineered to distribute the weight. Without attention to detail in the engineering design, the truss design will not be nearly as effective.

Bridges are very dynamic, but at U.S. Bridge, we can guarantee the highest-quality engineering that fits the environmental components of the build location.

The U.S. Bridge Steel Truss Bridge Designs

Several of our U.S. Bridge designs use steel trusses for optimal strength and durability. However, every truss bridge is different. Here are just a few of the truss constructions we’ve done in the past.

Pratt Truss — Liberty, Viking, Seneca, Voyager

Warren Truss — Cambridge, Cambridge Flat

Box Truss — Thru Truss
