Bridge Digital Twin Technology: Challenges and Benefits

Creating digital twins of bridges is useful for improving management, maintenance, and monitoring of physical infrastructure. Discover all the advantages

We all know that Digital twins have become important in the design workflows of buildings and infrastructure.

In this blog article, we will particularly focus on the potential that this technology offers to professionals responsible for bridge safety and monitoring.

You can start improving infrastructure management by using specially designed software solutions, such as:

a digital twin software enabling you to virtually create a replica of bridges and various infrastructure types, in addition to analysing, simulating, and optimising the real-time performance of physical resources;
a Bridge Management Software, a solution specifically designed to simplify bridge management and maintenance processes and ensure higher standards of quality, safety, and efficiency.

What is a Bridge Digital Twin

Digital twins are virtual models designed to accurately replicate real-world systems and objects.

Their application in engineering provides a detailed and interactive digital representation of construction projects (such as buildings, facilities, infrastructure, or entire cities).

The capability of digital twins to maintain constant communication with their physical counterparts has transformed these models into a powerful tool for designing, managing, and monitoring critical infrastructure, including bridges, viaducts, overpasses, and more.

In fact, the digital counterpart of a bridge, or a bridge digital twin, can be considered as the virtual copy of a real bridge. It serves as a centralized system through which all aspects related to safety, maintenance, and monitoring of the corresponding physical infrastructure can be managed.

How does a Bridge Digital Twin work

Digital twin technology relies on the integration of various advanced modeling processes and techniques to provide an accurate and reliable reconstruction of the characteristics and behavior of the real infrastructure.

First and foremost, the capabilities of Building Information Modeling (BIM) methodology can be leveraged to create a 3D digital model of the bridge, which can then be integrated with the necessary information to manage the entire life cycle of the structure.

However, creating a true digital twin requires the “digital twin” to be a “live” model that can interact constantly with its physical counterpart.

To achieve this, Internet of Things (IoT) devices and smart sensors are used to establish a bidirectional connection between the physical twin and the virtual twin.

Sensors placed at strategic points on the physical infrastructure collect real-time information regarding environmental conditions, material aging, structural safety, traffic impact, and more.

All this information is transmitted to a digital platform dedicated to monitoring and managing the digital twin, allowing it to process and analyze the data.

The entire process generates a reliable database that can be used as a support for subsequent management and maintenance operations of the real bridge, facilitating informed decision-making to improve overall efficiency and performance of the infrastructure.

Applications of Bridge Digital Twins

Digital twins of bridges and connecting infrastructure can be used for various purposes that help improve the functionality, safety, and efficiency of the respective physical assets.

The most significant applications include:

Performance and structural health monitoring through the use of sensors that detect potential problems and anomalies in real-time (such as cracks and deformations), allowing for timely intervention to prevent more severe damage;
Predictive maintenance by analyzing historical data and real-time information, helping predict maintenance needs and proactively schedule interventions (such as repairs or replacements), reducing unplanned downtime and extending the service life of the infrastructure;
Risk assessment through the collection, analysis, and simulation of data related to weather conditions, structural behavior, and traffic flows, allowing for the identification of potential risks and the implementation of preventive measures to enhance overall bridge safety;
Training and education through virtual or augmented reality simulations, allowing operators to simulate different scenarios and practice inspection, maintenance, and emergency response activities without risking their health and safety;
Decision support, as the collection of accurate and up-to-date data allows industry professionals to analyze the effectiveness of different maintenance strategies, evaluate their consequences in terms of cost, and make more informed decisions;
Performance optimization; the ability of digital twins to simulate hypothetical scenarios helps engineers assess their impact on the physical infrastructure, optimize design choices, and identify and address potential vulnerabilities in advance.
