Fire design
Due to increasingly stringent fire safety regulations and standards, fire design has become an integral part of everyday engineering work. Structural design now overlaps with fire protection planning, making the task far from straightforward. In Consteel, critical temperature calculation is implemented, and analysis can be conducted at both room and elevated temperatures. With these tools, our platform offers comprehensive solutions for the fire protection of structures, guiding you through this engineering challenge.

Specific Feature Solutions for Fire design in Consteel
Global buckling analysis
Global buckling analysis serves Consteel’s automatic stability design based on the General Method of EN 1993-1-1. It is a linear eigenvalue analysis performed on the whole structural model calculating the elastic critical load levels and connected buckling shapes showing the relevant modes of stability loss. All global buckling modes (flexural, torsional, and lateral-torsional buckling, and any interactions of these) are calculated, visualized and can be used for automatic design.
Critical temperature calculation
The fire design process is an integrated part of the Consteel automated and efficient design process. Depending on the designed fire protection solution, the structure can be unprotected or protected, in the latter case, the fire protection can be passive (insulation) or reactive (intumescent painting). The calculation can be performed with material properties at elevated or at room temperature. In the case of elevated temperature analysis, the indirect effects of thermal expansion can also be considered separately. For reactive protection, the critical temperatures are calculated for any steel member.

WHY CHOOSE CONSTEEL?
WHO RECOMMENDS US?

‘Consteel is a great asset for Arambol Ingeniería S.L. Thanks to its workflow we can design, calculate and present a project in record time. The program is very intuitive and easy to use. Technically, the seventh degree of freedom is an enormously useful tool to check structures with the general method, and even obtain reliable results thanks to the use of buckling shapes together with the imperfections to obtain utilization ratios that, physically, are more realistic than the reduction coefficients. Consteel has very specialized features such as the shear field or the frame corner wizard that add an extra degree of professionalism to the calculation, which translates into greater efficiency in the use of steel and, therefore, money.’

‘The Alba Arena project highlighted the extraordinary potential of the Consteel software and Pangolin. It is a pioneering technology that enables the parametric design of complex geometry and large-scale structures through the Grasshopper system. The Pangolin award is an exceptional recognition for me and the bim.GROUP, as it is a positive feedback on the quality of our work and an opportunity to showcase our expertise on an international level.’ said Dávid Lewandowski, Steel Structure Designer, regarding the award.’

‘Consteel’s technical support team is very professional. Especially Mr. Balint Vaszilievits-Sömjén, he has been a great help to us! We were impressed by his professionalism and dedication. We are satisfied with the use of Consteel, which has proven its worth in our international projects.’
‘I started using the Consteel design software during my university studies, when it was Consteel version 6. Even then I was impressed by the simplicity, transparency, and speed of the program. Since then, I have had the pleasure of designing many structures with the program, from small to large: industrial halls, office buildings, large opening roof structures, staircases, flying garages, pipe bridges, canopies, secondary closure elements, or the transmission line poles on which my doctoral thesis was based.
The bottom line is that it allows a structural engineer to model any structure in 3D in a structurally correct way, yet quickly and with a low risk of error. The most complex geometric type includes, for example, a lattice structure, where stability loss shapes can be efficiently calculated and sections optimised. One of my favourite features is the interpretability of the results, and the fact that the program receives significant updates year after year, which is the most user-oriented.’

‘From the very beginning, I really like Consteel because it can be used to perform global steel structure tests in a complex and compact way, efficiently. In addition, the software integrates well with automated parameter-driven design algorithms – so I can heartily recommend it.’


The approach of the Consteel team to software development also deserves praise, which shows a well-thought-out path of software development in terms of suitability for practical applications (and not only in terms of changing the graphic interface as is the case in other developers).
We recommend Consteel to all experienced engineers.’
