Structural Efficiency Of Cold-Formed Steel Purlins [PDF]

International conference KNOWLEDGE-BASED ORGANIZATION, 2015
Abstract Cold-formed steel structures represents an alternative to classic buildings made of hot rolled steel profiles which bring a lot of savings based on advanced calculations and also some practical measures in order to provide optimum strength and weight ratio. Due to these advantages, cold-formed steel structures are

INCREASING THE EFFICIENCY OF THE ROOF PURLIN SYSTEM

Modern structures of metal and wood, 2021
In the article, the authors consider one of the ways to solve the problem of reducing metal consumption and increasing the efficiency of metal structures by choosing an effective static scheme. The choice of the appropriate scheme is carried out for the most common elements of metal structures - beams, which also include roof purlins.

STRUCTURAL FIRE BEHAVIOUR OF Z PURLINS

Applications of Structural Fire Engineering, 2016
Cold-formed sections are very common and efficient as secondary load-caring structural members. But the current European design standard EN 1993-1-2 sets the limiting temperature for the Class 4 sections to 350°C which is generallyvery conservative approach.This paper is focused on the thin-walled profilebehaviourin case offire.

Fourier Series Approach for the Vibration of Euler–Bernoulli Beam under Moving Distributed Force: Application to Train Gust

Shock and Vibration, 2019
The dynamic response of an Euler–Bernoulli beam under moving distributed force is studied. By decomposing the distributed force into Fourier series and extending them to semi-infinite sine waves, the complex procedure for solving this problem is ...

Numerical analysis of the stability behaviour of castellated beams and comparison to regular hot‐rolled profiles

Steel Construction, Volume 19, Issue 1, Page 50-59, February 2026.
Abstract Castellated steel beams, characterised by their unique perforated web design, have gained significant popularity in the construction of medium‐span structures, like industrial and office buildings. These beams offer an economical solution due to their increased bending moment capacity about the major axis with relatively low weight and ...

Artificial Neural Network‐Based Optimization of Anaerobic Digestion in Municipal Wastewater Treatment

International Journal of Energy Research, Volume 2026, Issue 1, 2026.
Improving methane production is essential for enhancing the self‐sufficiency of wastewater treatment plants (WWTPs), with anaerobic digestion (AD) acting as the key sustainability driver by serving as an energy recovery mechanism. Artificial intelligence (AI) offers an effective way to manage the AD process without requiring a detailed understanding of

Design of an Innovative CFS Purlin (Zigmax®) by Experimental Testing

ce/papers, Volume 8, Issue 6, Page 337-342, December 2025.
Abstract ZIGMAX® is an innovative cold‐formed steel solution developed for roof purlins stabilized by steel sheeting or sandwich panels. This hybrid cross‐section merges the benefits of traditional Z and Σ profiles, delivering improved structural performance.
