Special Issue Information

Dear Colleagues,

The seismic performance of steel structures remains a key focus of civil engineering research due to their widespread application in high-risk seismic zones and their inherent ductility and adaptability.

This Special Issue will explore innovative methodologies aimed at enhancing the seismic resilience of steel structures, paying attention to both traditional and innovative seismic resisting steel systems and devices.

We welcome contributions addressing various aspects, including but not limited to the following:

  • Design and assessment of steel structures;
  • Numerical and experimental investigations;
  • Seismic hazard analyses;
  • Seismic loss estimation.

We look forward to your valuable contributions to this exciting Special Issue.

Dr. Silvia Costanzo
Guest Editor

This study investigates the robustness of steel moment-resisting frames (MRFs) under column loss scenarios, both in undamaged and post-seismic conditions. In this context, robustness is defined as the ability of a damaged structure to prevent progressive collapse following an earthquake. A parametric investigation was conducted on 48 three-dimensional MRF configurations, varying key design and geometric parameters such as the number of storeys, span length, and design load combinations. Nonlinear dynamic analyses were performed using realistic ground motions and column loss scenarios defined by UFC guidelines. The effects of pre-existing seismic damage, façade claddings, and joint typologies were explicitly accounted for using validated component-based modelling approaches. The results indicate that long-span, low-rise frames are more vulnerable to collapse initiation due to higher plastic demands, while higher-rise frames benefit from load redistribution through their increased redundancy. In detail, long-span, low-rise frames experience roughly ten times higher displacement demands than their short-span counterparts, and post-seismic damage has limited influence, yielding rotational demands within 5–10% of the undamaged case. The Reserve Displacement Ductility (RDR) ranges from approximately 6.3 for low-rise, long-span frames to 21.5 for high-rise frames, highlighting the significant role of geometry in post-seismic robustness. The post-seismic damage was found to have a limited influence on the dynamic displacement and rotational demands, suggesting that the robustness of steel MRFs after a moderate earthquake is largely comparable to that of the initially undamaged structure. These findings support the development of more accurate design and retrofit provisions for seismic and multi-hazard scenarios. Full article
