Digital Shield for Load-Bearing Structures: Russian Researchers Are Changing the Rules of Fire-Resistance Testing
A research team from Samara Polytechnic led by Denis Panfilov, head of the Reinforced Concrete Structures department, has developed a software package for electronic computing systems that makes it possible to more precisely evaluate the fire resistance of elements used in non-braced truss structures.
Traditionally, determining how long a reinforced concrete beam can withstand open flame requires physically burning the structure. The method is accurate, but expensive and time-consuming. Researchers at Samara National Research University named after Academician S.P. Korolev (Samara Polytechnic) have proposed an alternative. They created a software platform capable of calculating the fire resistance of structural elements virtually. The approach could become an important step toward the digitalization of Russia’s construction sector while also strengthening the industry’s technological sovereignty.
The Cost of Safety
Until recently, evaluating the fire-resistance limits of complex structures such as non-braced reinforced-concrete trusses – a type of load-bearing framework typically used in roofing systems without diagonal bracing elements – required full-scale fire tests. In these tests, engineers recreate a fire scenario in real time at a dedicated testing facility while sensors record the moment when the structure loses its load-bearing capacity. The methodology is reliable, but extremely resource-intensive. It requires specialized testing stands, substantial energy and material costs and, most importantly, each test effectively destroys the sample being evaluated. For large-scale construction design, this becomes a bottleneck. Engineers either build in excessive safety margins, increasing construction costs, or wait for access to testing facilities, delaying project timelines.
Samara Polytechnic’s Virtual Testing Ground
The Samara researchers’ system changes that equation. The software suite models how reinforced concrete behaves under high temperatures without physically heating the structure. The algorithms account for critical parameters including cross-sectional geometry, the depth and placement of reinforcement, the level of fire protection and the heating configuration used in the simulation. The software has already received official registration certificates and is ready for deployment.
This is not simply a “calculator,” but a full-scale engineering tool. It allows designers to vary structural parameters at early project stages and identify an optimal balance between material costs and required fire-resistance thresholds. For the construction-audit sector, that means building safety can be justified more quickly using calculation-based data already permitted under existing regulations. For residents, it could eventually translate into safer buildings where load-bearing structures have been evaluated with greater precision.
Part of the Digitalization and Import-Substitution Push
Russia’s construction industry is undergoing a deep transformation. Since 2024, the country has updated the rules governing digital information models for capital-construction projects, while the use of information modeling technologies (TIM/BIM) has become mandatory at many stages of a building’s lifecycle. Within that ecosystem, highly specialized engineering software is no longer optional – it is infrastructure.
Digital methods are steadily replacing older engineering workflows. During 2024 and 2025, other players in the market introduced similar tools, ranging from fire-protection calculation platforms developed by major manufacturers to advanced modeling systems used to justify the safety of metal structures. Samara Polytechnic’s development is positioned to become part of that broader shift. It also reduces dependence on foreign engineering software, which is often unavailable or poorly adapted to Russian regulatory standards.
From Academic Tool to Industrial Standard
The main challenge now is scaling. The developers have already announced plans to expand the platform to other categories of reinforced-concrete load-bearing elements. If the software evolves from a specialized truss-analysis solution into a universal engineering module, its value for design institutes could increase substantially.
Integration will likely become the decisive factor. The future of engineering analysis lies in seamless interoperability with Russian CAD systems and TIM platforms. If the Samara software learns to communicate with widely used domestic design environments, it could become a core component of the country’s digital construction workflow.
The Samara Polytechnic project illustrates how fundamental research can address applied industrial challenges. At a time when Russia is actively building and modernizing infrastructure, the shift toward digital safety-assurance methods appears increasingly inevitable. The software will not eliminate physical fire testing entirely, but it could make those tests less frequent and more targeted. Ultimately, that represents an investment in public safety: buildings designed with precise digital models are both safer and more reliable.
