Special Issue Information

Dear Colleagues,

Performance-based design represents a method to design the structures in order to achieve specific performance goals or aims, rather than following the code provisions or standard rules. In this way, with fixed specific performance expectations, the structural behavior is evaluated and optimized according to these criteria. The performance-based approach can be applied to existing or new structures as well as different structural typologies (reinforced concrete structures, masonry structures, steel moment frames, etc.).

In recent decades, researchers, engineers and designers have focused their attention on performance-based design by adopting advanced simulation and modelling tools, involving the evaluation of how a structure would perform under various conditions, such as wind, seismic actions, and fire, and, to optimize the design.

The main aim of this Special Issue is to depict the key issues in the application of performance-based design for structures subjected to various loading actions. More specifically, this Special Issue will focus on recent developments, challenges and limitations, case studies, and design codes.

Example topics of interest include, but are not limited to, the following:

  • New design methodologies;
  • Stochastic and deterministic methods;
  • New approaches in the retrofitting strategies;
  • Evaluation of soil–foundation interaction.
  • New dissipative joint connections;
  • Seismic vulnerability assessment;
  • Dynamic analysis of structures.

Seismic Performance of Moment-Resisting–Eccentrically Braced Dual Frame Equipped with Detachable Links

Abstract
Moment-resisting frames (MRFs) and eccentrically braced frames (EBFs) can be effectively combined in multi-story steel buildings. In fact, MRFs provide redundancy and ductility, while EBFs provide initial and post-yield stiffness with high energy dissipation capacity. In addition, if detachable links are designed as [...] Read more.
Moment-resisting frames (MRFs) and eccentrically braced frames (EBFs) can be effectively combined in multi-story steel buildings. In fact, MRFs provide redundancy and ductility, while EBFs provide initial and post-yield stiffness with high energy dissipation capacity. In addition, if detachable links are designed as dissipative fuses, it is possible to activate their almost contemporary yielding and prevent the collapse of structures during severe earthquakes, ensuring easy repair and rehabilitation measures. The seismic responses of dual frames with MRFs and EBFs are investigated by means of pushover analyses. Different buildings were designed, varying the number of floors (two, four, and eight stories), the number of MRF spans (zero, one, and two), and the length of the short links (0.8 Mp/Vp and 1.6 Mp/Vp). The obtained results confirmed the superior behavior of dual frames with respect to simple EBFs. In addition, it was observed that the frames with the shorter links exhibited higher resistance and rigidity but smaller overall displacement capacity because of the anticipated failure of the links.

In 2007, the American Iron and Steel Institute (AISI) established a standard for cold-formed steel–special bolted moment frames (CFS-SBMFs). This structural system is designed to resist seismic forces. The CFS-SBMF system employs double-channel beams and square hollow structural section (HSS) columns that are bolted together to create a sturdy and robust structural frame. However, the CFS-SBMF system is only suitable for constructing one-storey buildings, and ASCE 7 prohibits its use in buildings with a height of over one storey. This study was conducted to expand the use of CFS-SBMFs to the construction of multi-storey low-rise buildings. Firstly, a new moment connection detail is proposed, and a design procedure is proposed to ensure that bolted connections, instead of beams or columns, have the ductility to withstand seismic forces. Secondly, the proposed design procedure for bolted connections was verified through full-scale cyclic testing. Finally, a comprehensive evaluation was undertaken to evaluate the proposed structural system’s performance under seismic excitation. The evaluation included nonlinear dynamic analysis and incremental dynamic analysis (IDA) according to FEMA P695, which provided a detailed understanding of the seismic design factors (SDFs) in multi-storey low-rise CFS-SBMF buildings.

The main aim of this work is to validate the application of a simplified performance-based method for assessing the seismic performance of steel buildings, focusing particularly on Moment Resisting Frames (MRFs) through nonlinear analyses. This simplified method defines the capacity curve of a structure through elastic and rigid-plastic analyses, calibrated by regression analyses conducted on 420 structures. To assess its accuracy, the method was compared with other analytical approaches, including incremental dynamic analyses (IDA) provided by existing codes. These analyses were performed on both real structures and simulated designs, considering recent and older codes. The comparison of capacity results derived from code-based approaches and IDA, aligned with the limit states outlined in current codes, showcased the high reliability of the proposed simplified assessment approach.
