Bridges to the future

The German autobahn network has aged. Thousands of bridges, built in the 1960s and 1970s as masterpieces of engineering, now face a tremendous test. The steadily increasing heavy traffic and the effects of time take their toll. fischer rises to this challenge and provides the right solutions: With innovative fastening technology, solid scientific expertise, and digital planning tools, the path is paved for a safe and durable infrastructure.

When Concrete Makes History: The Renovation Initiative

The figures from the Federal Ministry for Digital and Transport (BMDV) speak clearly: Around 12,200 bridges in the federal road and rail network urgently need rejuvenation. Whether strengthening, renovation, or a complete replacement build – maintenance is one of the central tasks for the coming decades. The principle applies: preservation before demolition. Where the building fabric allows, targeted measures extend the service life and permanently ensure safety for traffic.

Safety as a Foundation

There is no room for compromise in construction. Prof. Dr.-Ing. Akanshu Sharma (Purdue University) and Prof. Dr.-Ing. Jan Hofmann (University of Stuttgart) emphasize the urgency: even the smallest partial damages can jeopardize structural integrity. Fastening technology is the crucial link in this regard. Only when the safety of individual components – from the plug to the anchor – perfectly harmonizes with the overall construction does trust in the infrastructure remain intact.

Safety as the highest priority
The goal of modern safety concepts is to reduce the risk of structural failure to an acceptable minimum

Technology that connects: The fischer portfolio

fischer provides the tools for this demanding task. Johannes Braun, expert in Digital Product Services, emphasizes the holistic approach: “The systems enable far more than just classic concrete repair. They are the key to reinforcing existing concrete and reinforced concrete components.”

The portfolio includes highly specialized solutions for bridge construction.

    BRIDGE-FIX: The Digital Revolution in Planning

    The planning of bridge caps is a complex undertaking, where wind loads, impact forces, and material deformations must be calculated precisely. This is where the web-based tool BRIDGE-FIX sets new standards.

    Dr. Erik Johannes Stehle, Head of Development FiXperience at fischer, describes the progress: “BRIDGE-FIX ends the era of manual Excel spreadsheets.” The tool offers planners decisive advantages:

    • Direct access: Browser-based and without complex software installation.
    • Standards compliance: Current standards are firmly integrated into the calculation logic.
    • Maximum transparency: Traceable proofs supported by independent expert reports from Prof. Dr. Jan Hofmann.

    Bridge Renovation: Together for a Stable Infrastructure

    The renovation of German bridges is a major challenge that requires technological precision and visionary thinking. By combining powerful fastening technology, scientific excellence, and digital solutions like BRIDGE-FIX, fischer makes a decisive contribution to ensuring that today’s transport routes also meet the demands of tomorrow.
