On Monday, 22 June 2026, from 4:00 p.m. to 5:00 p.m. in Room 141 of the Faculty of Civil Engineering in Belgrade, the second SAEE lecture "Design of steel frames for earthquake resistance" was held.
The lecture was delivered by Assoc. Prof. Primož Može, PhD; Chair of Metal Structures Faculty of Civil and Geodetic Engineering, University of Ljubljana.
Below you can find the lecture abstract and the speaker biography.
Abstract:
Steel is a highly ductile material and is therefore particularly suitable for use in structures located in seismic areas. However, the 1994 Northridge earthquake revealed damage and fractures in steel frames that were previously considered earthquake-resistant. This event was one of the catalysts for extensive research into the ductility and resistance requirements of steel frames, which led to the development of modern standards for the seismic design of steel structures, including the first generation of Eurocode 8 (EC 8) issued in 2005, followed by the second generation, which must become mandatory by 2028.The lecture outlines the fundamental principles of seismic design, with particular emphasis on ductility, energy dissipation, and capacity design. Seismic analysis is briefly explained, focusing on key aspects specific to steel structures. The use of behaviour factors to reduce seismic effects based on the expected ductility of the structure is discussed. The concept of controlled structural behaviour is highlighted, where selected dissipative elements undergo inelastic deformation, while the remaining parts of the structure are protected using overstrength factors. The behaviour of energy dissipation mechanisms, such as plastic hinges in bending, shear links, and tension braces, is examined in detail, including cyclic behaviour and hysteretic response. Design rules for joints are emphasised, particularly the preference for full-strength connections near dissipative zones. A significant part of the lecture focuses on ensuring both local and global ductility. Local ductility is achieved through appropriate cross-section classification, material selection, and detailing of dissipative zones, while global ductility is ensured through suitable collapse mechanisms. The focus is on moment-resisting frames, concentrically braced frames, and eccentrically braced frames. Emphasis is placed on the design rules provided in the first generation of EC 8, along with the key improvements introduced in the second generation of EC 8.
Presenter biography:
Assoc. Prof. Primož Može is a professor of steel and composite structures at the Faculty of Civil and Geodetic Engineering, University of Ljubljana, where he holds several positions. His main research areas include joints in steel structures, high-strength steel, and the stability of plated structures. He was a member of the project team responsible for developing the second generation of the Eurocode for the design of joints in steel structures, and is an active member of CEN TC 250/SC 3 WG 8 and ECCS TC 10. He has authored several articles in leading international journals, served as editor of a special issue on Joints and connections with fasteners for resilient steel structures for the Journal of Constructional Steel Research, and is editor-in-chief of the Slovenian journal Gradbeni Vestnik. He was responsible for Slovenian coordination of several European and national projects. He is also president of the Slovenian Association of Structural Engineers and vice-president of the Slovenian mirror group to CEN TC 250/SC 3 and of ECCS TC 10.
