Class 4, thin-walled sections

Using slender, welded thin-walled sections has become a real trend in the construction industry over the past decades. The drive to save material makes cross-sections thinner, while behavior and failure modes become much more complicated, requiring more advanced analysis and design tools.

No credit card required

How can engineers efficiently leverage the benefits of thin-walled sections while handling this design complexity and ensuring structural integrity?

With Consteel, engineers can seamlessly incorporate thin-walled sections into their projects, unlocking new levels of efficiency and performance by using 7 DOF members.

Class 4, thin-walled sections specific feature solutions in Consteel

User defined thin-walled section drawing

Besides several parametrically defined sections, custom profiles can also be created in Consteel. Profile definition includes not only drawing geometry but setting parameters necessary to Consteel’s automated design options too. These are standard Eurocode parameters of cross sections used for the automatic stability check, local buckling and distorsional buckling in case of cold-formed sections. Ultimately, manually defined cross-sections can be fully integrated into Consteel’s highly automated design workflow, just like standard or built-in macro cross-sections.

Easy modeling of nonunifrom members – Tapered members

In Consteel, the tapered members are easy to define with just a few clicks and with the help of realistic visulalisation, despite of the numerous options provided for geometry. Member eccentricities due to placement options are recognized and considered automatically during analysis, as well as the special calculation method serving the correct transfer of warping between the finite elements of different heights.

Easy modeling of plated girders – Superbeam

Considering shear and rotational restraints provided by the various types of sheeting is unavoidable during cold-formed purlin design. In Consteel, the definition of these restraints is practical for everyday use and supplemented with an automatically applied special purlin design mode of analysis and design calculations. As purlins can be modelled as integrated parts of the structural model, their restraining effect to the main structure can also be considered.

Exact analysis of structural eccentricities

In Consteel, the structure can be modelled as it is in reality concerning eccentricities too. Deformations and internal forces caused by the eccentricities of loads, supports or connections are fully considered. No further action is needed after correct modelling to apply the effects in design calculations.

True analysis of global steel structures – the 7 DOF beam element

Consteel is the only structural design software that uses the special 7 degrees-of-freedom (7 DOF) beam element for all the global structural analysis types. The 7 DOF element is specially developed for thin-walled members where the warping of the cross-section is of high importance in the behavior. Modeling is always done in 3D and various number of analysis types including special and unique ones (like global buckling, buckling sensitivity or imperfection analysis) are developed to assist you to get to know the true behavior of your structure and design it optimally.

Innovative formwork design with Pangolin

Introducing the one of the winners of The Steel Lion Award 2024. The article includes a detailed case study of Pangolin design for the creation and design of formwork structure.

Control throughout the design process is crucial, and even more so when it comes to structures whose loads change throughout the design process, as they are the result of a phased analysis that aims for an optimum.The field of special formwork is one of these areas.Structures that: must support large loads (weight of fresh concrete) without showing large deformations to obtain the required concrete geometry, with the lowest po…
