Special Issue Information

Dear Colleagues,

The notion of “smart structure” integrates promises of disaster resilience, generally incorporating the capacities for civil structures to anticipate, react, respond, and reorganize after being subjected to natural and human-made disturbances. Dealing with this, the emerging artificial intelligence (AI) and the state-of-the-art industrial technology (covering vibration control and structural health monitoring) are heralded as integrated means for enhancing resilience. With the rapid development of AI-enabled civil engineering, it appears that timely assessment, prediction, and improvement of urban resilience can be realized. Despite the critical progress, it remains challenging to promote research advances in theory, experiments, framework, and, above all, applications that are helpful to improve the safety of metropolitan areas by mitigating socio-economic losses in case of extreme disasters.

This Special Issue on “Next-Generation Intelligent and Resilient Structures” aims to bring together cutting-edge development in emerging AI technologies for resilient civil infrastructural systems. Further, recent developments in novel structural health monitoring, vibration control, and construction are of interest. This Special Issue welcomes original contributions containing fundamental research, case studies, opinion papers, and review articles. The desired topics include but are not limited to the following:

  • AI in civil infrastructural systems;
  • Emerging vibration control and isolation;
  • Efficient design methods for optimal structural control;
  • Seismic vulnerability assessment;
  • Resilience upgrading technologies;
  • AI-based structural health monitoring;
  • Mechanical metamaterial.

Viscous dampers have proven to be effective in enhancing the seismic performance of existing structures. Despite this, there is still a need for rapid and simplified design methods and formulae for viscous dampers that can take into account the elastic–plastic performance of structures. This study introduces a retrofit design method for existing structures using viscous dampers, based on the concept of uniform damping ratio (UDR), with the aim of fully utilizing each damper. The UDR concept assumes that each damper in the structure provides the same UDR when subjected to seismic excitations of identical intensity. In this method, the first step involves defining the equivalent damping ratio (EDR) of the damper. Then, based on the capacity spectrum of the structure, the response mitigation ratio can be determined, which helps to determine the additional EDR required from the dampers. Once the UDR and additional EDR from the viscous damper have been determined, the parameters of the dampers at each story can be rapidly obtained. To demonstrate the effectiveness of this method, a six-story reinforced concrete frame was utilized as a benchmark structure. A comparison between this UDR-based approach and a traditional design approach was also conducted. The study findings reveal that the UDR concept enables the maximum utilization of energy dissipation capacity of viscous dampers installed in the structure, leading to a more effective and economical design approach.

The aim of this study is to investigate the performance of isolated structures by considering the possibility of impact under severe earthquakes. In the design of isolated structures, the required displacement capacity is determined based on the considered earthquake hazard level. However, there is a possibility of an impact caused by moat walls or adjacent structures under severe earthquakes. Dampers are used in this study to improve the performance of structural and nonstructural components. In this regard, three isolated structures (6, 9, and 12 stories) equipped with Triple Friction Pendulum Isolator (TFPI) are designed under earthquake hazard levels of BSE-1 with return periods of 475 years. Based on the different positions of these three structures relative to each other, four scenarios are defined to investigate the effect of impact. Modified endurance time (MET) method, as a cost-efficient nonlinear time history analysis method, is employed for structural evaluation under variable earthquake hazard levels. The placement of dampers is also taken into account in evaluating the effect of dampers. Therefore, the structures have been retrofitted once by adding damping and stiffness devices (ADAS) on the stories and once by adding fluid viscous dampers (FVD) at the isolated level. Results indicate that structures might collapse under earthquake hazard levels of BSE-2 with return periods of 2475 years. This matter is influenced by the adjacency of two isolated structures next to each other, and the severity of this fact depends on the height of the structures and the displacement capacity of the isolators so that the tall, isolated structures have decreased the performance of the adjacent shorter isolated structure. Moreover, the placement of dampers has a significant influence on the performance of structural and nonstructural components, depending on the reason for the impact. Full article

To resolve the problem of the super-long steel structures producing high-temperature stress on the lower concrete roof column section and improve the structure’s seismic performance, in this paper, we introduce a type of composite damped hinge bearing (CDHB). Firstly, this paper introduces the detailed construction of the CDHB and elaborates on its working principle. The mechanical properties of a CDHB have been tested, including the monotonic loading test on the whole bearing and the reciprocal loading test on the built-in dampers. The CDHB’s working performance, rotation performance, and energy consumption performance under tensile and compressive forces are also discussed in this paper. The study results show that: (1) Generally, the vertical deformation of the CDHB increases linearly with the increase of compressive and tensile forces, while it decreases with the increase of initial displacement. (2) Under vertical loading, the CDHB can reach a turning angle of 0.6 rad. The bearing is more likely to rotate with the increase in initial displacement. (3) The ultimate displacement, maximum damping force, damping constant, and damping coefficient of the built-in dampers are all stable. Full article
