Iranian Experts Introduce New System to Obviate Restrictions in Steel Structures
Farid Mahmoudi Sahebi, a PhD graduate of Amirkabir University of Technology, under the guidance and supervision of Alireza Rahayee and Farzad Hatami, faculty members of the university, implemented a project titled ‘Studying the Performance of the Shear Link Frame System’.
“In this project, after numerical prototyping of the shear link frame system, laboratory samples were constructed, and this idea has now been validated numerically and in the laboratory,” said Mahmoudi Sahebi.
Noting that one of the challenges of this research was testing multi-span frames, which were implemented in the country in cooperation with the technical team of the Neka Machine Steel Factory, he said that the results of this research is applicable to the steel structure construction industry.
"In addition to providing suitable architectural space for installing openings, this system increases the possibility of repairing the structure due to the replaceability of its components; while the results of our research show that this system can be a suitable alternative to divergent braces and bending frames in short spans," Mahmoudi Sahebi said.
In a relevant development in May, a technological company in Iran had succeeded in designing and producing a cable collector system without carbon brush that is used in the steel, iron smelting, and tractor manufacturing industries to prevent surface vibration.
“Industrial cable collector without carbon brush, usable in various industries, is a system for replacing all devices that use carbon brush,” Behnam Alizadeh Qeshlaq, the managing-director of the company, told ANA on the sidelines of Asr-e Omid event in the Northwestern city of Tabriz.
He explained that the carbon brush, which is indigenized by the company, was previously imported to Iran, adding, “The company’s main goal is to reduce the number of industrial collector cables with carbon brush that are widely used in steel factories, iron smelting plants, and tractor manufacturing companies.”
“The problem with carbon brushes was that slipping and surface vibration caused sparks and stopped production lines and furnace charging,” Alizadeh Qeshlaq said.
Noting that the project has started since two years ago, he said, “Our system is working without stop or failure, and no reports of malfunctions have been reported yet.”
