About the Project
The M1 motorway signage upgrade demanded a cantilever ring structure supported by a steel grillage substructure, secured with screw piles on a slope embankment. Positioned over one of England’s busiest motorways, this independent verification project required meticulous calculation and modeling to ensure the structure met stringent Eurocode standards, particularly for fatigue under high traffic load conditions.
Richter Associates, a Polish-based engineering firm specializing in temporary works and ground engineering, undertook the project. The team, led by Principal Engineer Maciej Adamczyk, combined expertise in temporary works and connection design to deliver an efficient and accurate solution. This project highlighted Richter Associates’ ability to integrate innovative tools like IDEA StatiCa into their workflows to achieve both technical excellence and client satisfaction.
Engineering Challenges
This project presented a range of technical and logistical challenges. The cantilever ring structure, located on a slope embankment, needed to endure repetitive traffic-induced loads and accidental collision forces while meeting the strict fatigue and robustness requirements outlined in CD 365 and Eurocode standards. Fatigue checks were required for all structural members and plates, particularly welds, bolts, and stiffeners, where high-utilization stress peaks were most likely. IDEA StatiCa was critical in quickly and accurately determining stress ranges in all parts, a capability unmatched by other software.
Fatigue checks for all structural members and plates of the gantry were crucial. IDEA StatiCa allowed us to very quickly and accurately determine stress ranges in all parts, including the welds, which no other software could achieve in the required timeframes

Collision forces, which were not part of the original design specification, introduced additional complexity. These forces significantly impacted the utilization of steel plates and bolts, requiring sophisticated analysis to ensure compliance without overdesign. The structure also relied on 12 screw piles to stabilize and distribute loads across variable soil conditions, further complicating the verification process.
Initially, the team planned to verify each connection individually. However, given the number of interdependent elements, this approach proved inefficient. Instead, the team adopted a global modeling approach using IDEA StatiCa, enabling them to analyze all connections simultaneously and streamline the process. The fast-paced UK temporary works market added further pressure, necessitating a solution that could deliver results within tight deadlines without compromising accuracy or compliance.
Using IDEA StatiCa for this project allowed us to save significant time, quickly addressing all stress and fatigue requirements. In the British market, where fast turnaround is crucial, this was a game-changer.

Solutions and Results
The workflow began with Tekla Structural Designer for base-level modeling, which provided insights into load distributions and pile reactions under standard conditions. From the outset, the team planned to use IDEA StatiCa Connection for detailed connection checks, but as the project evolved, the scope expanded to cover all structural elements in a single model. This shift to a global model, facilitated by IDEA StatiCa’s Component-Based Finite Element Method (CBFEM), allowed Richter Associates to analyze complex load combinations, stress peaks, and fatigue effects comprehensively.
IDEA StatiCa’s flexibility in shaping connections using stiffening members and plates proved invaluable. These tools enabled the team to define intricate details and assess their behavior under specific loading conditions, ensuring compliance with CD 365 and Eurocode fatigue standards. One of the software’s standout features was its ability to consolidate multiple connection checks into a single model, dramatically improving workflow efficiency and accuracy. By adopting this approach, the team not only saved significant time but also ensured consistent results across all elements of the structure.
The ability to analyze whole sections of the structure with multiple connections in one model made the design process faster and more accurate.

The software also addressed challenges related to robustness requirements. The gantry was verified for increased impact forces without requiring redesign or strengthening, avoiding unnecessary costs and delays. IDEA StatiCa’s automated reporting further enhanced the process by providing professional, high-quality outputs that exceeded client expectations, simplifying communication and enhancing stakeholder confidence.
This project showed how efficient IDEA StatiCa is when we need precise checks under complex loads. Its usability for independent verification work is unmatched.

This project underscored IDEA StatiCa’s unique value as more than just a connection design tool. Its ability to analyze entire sections of a structure with multiple connections in a single model made it an indispensable solution for complex projects. The combination of flexibility, speed, and accuracy, along with its automated reporting capabilities, demonstrated how IDEA StatiCa can transform workflows and meet the most demanding project requirements.
