Special Issue Information

Dear Colleagues,

The main aim of this Special Issue is to rapidly disseminate state-of-the-art experimental, theoretical, computational and/or numerical research in sustainable and resilient steel structures. Studies investigating structural components, systems or portfolios of structures fall within the scope of this Special Issue. Specifically, studies targeting the effect of extreme single and multiple hazards on the sustainability and resilience of steel structures are encouraged. Studies with practical implications for the profession and practice of structural engineering are welcome. The research published in this Special Issue will have a positive impact on the design, analysis, repair, maintenance, sustainability and resilience of steel infrastructures (buildings, bridges, transmission towers, offshore structures, steel pipelines, among others). Potential authors can contact the Guest Editors if they would like to discuss the suitability of their work for this Special Issue.

Topics of interest include, but are not limited to, the following aspects of sustainable and resilient steel structures:

  • Performance-based design or analysis criteria;
  • Life-cycle cost assessment and optimization;
  • Improving the sustainability of steel infrastructures;
  • Modeling of steel structures subjected to single or multiple hazards;
  • Innovative structural steel systems;
  • Novel connections and fastening systems;
  • Repair and restoration following extreme events;
  • Innovative design solutions for complex steel infrastructure challenges;
  • Design and assessment issues with high-rise buildings, offshore structures, transmission towers and pipelines under extreme loads;
  • Data science in steel infrastructures (inclusive of structural health monitoring);
  • Sensors for monitoring steel infrastructures;
  • Frame optimization and sensitivity analysis;
  • Topology optimization of structural members and connections;
  • Cast steel components.

Abstract
Special concentrically braced frames (SCBFs) located in regions close to earthquake faults may be subjected to near-fault ground motions, often characterized by pulses with long periods. These near-fault pulses could impose additional seismic demands on structures and increase the risk for structural collapse. [...] Read more.
Special concentrically braced frames (SCBFs) located in regions close to earthquake faults may be subjected to near-fault ground motions, often characterized by pulses with long periods. These near-fault pulses could impose additional seismic demands on structures and increase the risk for structural collapse. Currently, there is limited research on the seismic collapse risk of SCBFs under near-fault earthquakes. This paper uses a general simulation-based framework to assess the seismic collapse risk of SCBFs under near-fault earthquakes. To quantify the large variability and uncertainty associated with the seismic hazard, a stochastic ground motion (SGM) model is used where the near-fault pulse characteristics are explicitly incorporated. The uncertainties in the SGM model parameters (including the near-fault pulse characteristics) are addressed through appropriate selection of probability distribution functions. To accurately predict the occurrence of collapse, numerical models capable of capturing the nonlinear and collapse behavior are established and used. Efficient stochastic simulation approaches are proposed to estimate the seismic collapse risk with or without considering the near-fault pulse. As an illustration, the seismic collapse risks of two SCBFs are investigated and compared. Probabilistic sensitivity analysis is also carried out to investigate the importance of uncertain model parameters within the SGM towards the seismic collapse risk. Full article

This paper presents the behaviour and design procedure of bolted connections which tend to be sensitive to block shear failure. The finite element method is employed to examine the block shear failure. The research-oriented finite element method (RFEM) model is validated with the results of experimental tests. The validated model is used to verify the component-based FEM (CBFEM) model, which combines the analysis of internal forces by the finite element method and design of plates, bolts and welds by the component method (CM). The CBFEM model is verified by an analytical solution based on existing formulas. The method is developed for the design of generally loaded complicated joints, where the distribution of internal forces is complex. The resistance of the steel plates is controlled by limiting the plastic strain of plates and the strength of connectors, e.g., welds, bolts and anchor bolts. The design of plates at a post-critical stage is available to allow local buckling of slender plates. The prediction of the initial stiffness and the deformation capacity is included natively. Finally, a sensitivity study is prepared. The studied parameters include gusset plate thickness and pitch distance. Full article

Steel plate shear walls (SPSWs) have advantages such as high elastic stiffness, stable hysteresis behavior, high energy absorption capacity, and decent ductility. However, one of the main drawbacks of SPSWs is their buckling under lateral loading. To address this issue, a simple and practical solution in the form of using a trapezoidal plate moment connection (PMC) and a narrow gap between the infill plate and columns is presented. The PMC will act as an energy absorber, similar to a yielding steel plate, and keep the other structural members in an elastic state. Extensive three-dimensional finite element (FE) models of the SPSW system were investigated under monotonic and cyclic loading. The results revealed that by separating the infill plate from the vertical boundary elements and using two vertical edge stiffeners at both edges of the wall, the same lateral bearing capacity of the conventional system can be achieved. In addition, by increasing the thickness of the PMC from 6.5 to 26 mm, the load-bearing capacity, energy dissipation, and elastic stiffness increased approximately 2, 2.5, and 3.2 times, respectively. It was also found that the flexural capacity ratio of the connection to the beam had little effect on the overall force–displacement behavior. However, it can affect the system failure mechanism. Finally, the tension field inclination angle for such SPSWs was proposed in the range of 30 to 35°. Full article
