Distortional buckling of cold-formed profiles

Distortional buckling is the most complex and consequently least recognized design problem, fundamentally influencing the efficiency of the rapidly evolving sector of cold-formed structures. Whether it’s new product development or simply purlin design, Consteel serves as a reliable partner in your work.

Our platform is uniquely tailored to meet the demands of designing structures with cold-formed profiles, boasting fundamental functionalities that align seamlessly with these requirements. Complemented by targeted features, our platform offers a comprehensive solution for optimization.

With Consteel’s toolset at your disposal, each project becomes a journey of exploration and fulfillment, reigniting the excitement and fascination inherent in structural engineering.

Distortional buckling of cold-formed profiles specific feature solutions in Consteel

Parametric cold-formed profiles

Extended possibilities are provided for our users to define the most commonly used types of cold-formed sections parametrically. Z, C, Sigma, Zeta, hat, L and closed profiles are all available with possible web, flange and edge stiffeners where applicable. Definition is straightforward and design is handled through General Method in a fully Eurocode-conform way with the consideration of supplementary rules of EN 1993-1-3.

Easy modeling of purlins – Purlinline

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.

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.

Purlin design

Purlin design is always filled with questions. Consteel provides a comprehensive solution with its special purlin design mode: consideration of the restraining effect of the sheeting, the overlaps and complete, Eurocode-conform local and distortional buckling design.
Since purlins can be modelled as integrated parts of the global structural model, the different stiffnesses of their supports (the frames) can be examined, as well as the purlins’ stabilization effect on the frames.

How can consteel enhance your work?

Advanced modeling and structural analysis of photovoltaic tracking systems

This time, we will take a look at the pioneering technologies used and developed by one of our customers, as well as the implementation in Consteel software for the structural design process, which has allowed them to evaluate and design to the significant loads that a solar panel support structure can be subjected to. The benefits of using Consteel in terms of workflow and productivity will also be demonstrated.

Array Technologies (STI Norland) is a company founded in Spain dedicated to the construction and implementation of photovoltaic utilization projects, including both tracking systems and fixed systems. In 2002, it built the world’s first solar tracking plant in Navarra.
