In the fast-paced world of industrial facility development, delivering structurally sound and code-compliant designs within tight timelines is a challenge. This case study explores the successful design and detailing of a steel warehouse with an integrated crane system, located in Serbia. Faced with uncertainties and the need for high-speed delivery, the engineering team at Stavba-Projekt d.o.o. used IDEA StatiCa Connection to speed up connection design and meet Eurocode standards without compromising safety or precision.

About the Project

The project involved the design of a steel warehouse equipped with a crane system capable of handling significant dynamic loads. Located in Serbia, the structure was subject to Eurocode regulations alongside the Serbian National Annex. The warehouse’s core challenge lay in the complexity of steel connections that needed to safely support the operational stresses of crane movements.

Stavba-Projekt d.o.o., a family-owned structural engineering firm based in Bački Petrovac, handled the design. With a compact team of just two engineers, the company has been delivering expert engineering, design, and consulting services since 1989. Structural engineer Peter Benka played a central role in this project, overseeing the modeling, analysis, and optimization of the steel structure and its connections. The overall structural design was performed using Radimpex Tower, while IDEA StatiCa was used specifically for steel connection analysis and optimization.

Engineering Challenges

The initial obstacle was the absence of a finalized crane specification. The investor had not selected a crane model, which meant that load data essential for connection and crane rail design was missing. This created a significant risk of delays and inefficiencies. Additionally, the tight timeline typical of commercial developments demanded a design process that was not only fast but rigorously code-compliant.

Hand calculations for complex steel connections would have been time-consuming and inefficient, especially under the pressure of tight project deadlines.

Another critical challenge stemmed from the need to address both static and dynamic loads imposed by the crane system. Traditional hand calculations would have been far too time-consuming and error-prone, particularly when working with Eurocode 3 requirements and dynamic load variations. Manually verifying connection compliance for multiple load combinations would have added unacceptable risk and workload to the small team.

Solutions and Results

To work around the lack of crane data, the team developed a generic model of the warehouse and crane structure based on typical specifications. This provided a flexible framework that allowed progress to continue without waiting on final details. When the exact crane data became available, the design was swiftly adapted using IDEA StatiCa’s advanced features.

IDEA StatiCa's automation capabilities allowed the team to redesign and verify complex steel connections—such as column anchoring, crane girder-to-beam interfaces, and dynamic load-bearing joints—in just a few hours. The software’s automated code-checking against Eurocode 3 ensured the structural safety and legal compliance of every connection.

Once the specific crane details were received, the steel connections could be quickly adjusted and verified to match the exact load conditions.

The benefits extended beyond the design phase. Using IDEA StatiCa Connection’s 3D visualization features and Bill of Materials output, the team improved on-site communication with contractors. During construction, this enabled quick resolution of technical questions and seamless coordination between engineering and fabrication teams.

Ultimately, the project was completed on time and within budget. IDEA StatiCa proved instrumental in turning a high-risk scenario into a streamlined, confident design process.

Conclusion

This project demonstrated how a well-chosen digital workflow can turn uncertainty into a manageable design variable rather than a project risk. By relying on IDEA StatiCa for fast, reliable connection design and verification, the engineering team was able to remain flexible, respond immediately to late design inputs, and maintain full confidence in safety and compliance. Beyond time savings, the software supported clearer communication across all project stages, from design refinement to on-site execution, resulting in a smoother delivery process and a structure that met both technical and commercial expectations.
