Special Issue Information

Dear Colleagues,

It is our pleasure to invite you to contribute to this Special Issue, titled “Sustainability in Structure Engineering of Seismic and Shock Resistance Resilience Designs and Assessments”.

Earthquakes and shock risk disasters can cause serious damage to engineering structures or traffic infrastructure and, even worse, induce their collapse. Recently, the concept of sustainable resilience has gained increasing importance in the design and assessment of newly built or rehabilitation structures, particularly buildings, bridges and underground engineering exposed to manmade and natural hazards, such as earthquakes and shock disasters.

Conventional structures are designed using performance-based seismic methods, mainly considering ductility and energy consumption through the plastic deformation of structural members, and are expected to not collapse after earthquakes and shock disasters, in order to protect life. However, damage accumulates in ductile structures, and repair work due to serious plastic deformation is unavoidable after disasters, causing huge economic losses. These represent considerable costs associated with the disruption of business operations and significant obstacles to post-disaster emergency response, and result in the prolonged disruption of regional or even national economies. Therefore, sustainable seismic and shock resistance resilience designs and assessments are required to ensure that structural function or normal operation can be recovered quickly after disasters, which has attracted much attention in recent years. Many high-performance resilient systems have been developed, such as rocking structures, self-centering structures, damper-added structures, base-isolated structures, etc. In addition, many components or devices that are replaceable, self-centering, or feature energy dissipation have also been extensively studied to enhance their resilience. This development is also accompanied by the advance in design and evaluation methods.

This Special Issue welcomes contributions towards filling the seismic design and resilience assessment, sustainable assessment and modelling in shock risk mitigation and enhancing resilience in face of disasters for engineering structure and infrastructure in seismically active regions or shock risk disaster mountainous areas.

For this Special Issue, original research articles and reviews are welcome. Research areas may include (but are not limited to) the following:

Seismic resilience design and assessment;
Sustainable assessment and modelling in shock risk mitigation;
Seismic optimization and retrofit decision making;
Time-dependent seismic or shock risk assessment;
Multi-risk analysis;
Enhancing resilience in the face of disasters;
Seismic-resilience-based design methods;
Evaluation of structural impact resistance performance.

We look forward to receiving your contributions.

Sustainable Seismic Performance of Diagrid Core-Tube Structure with Replaceable Steel Coupling Beam

by Chengqing Liu, Guang Li, Bin He, Cong Zhou and Ying Ma

Abstract

The diagrid core-tube structure has been widely used in high-rise buildings in recent years, but there are few studies on the sustainable energy dissipation measures and seismic performance improvement of such structural systems. Because the coupling beam is the element connecting the inner tube and the outer tube in the diagrid structure, it is the first seismic defense line and an important energy-dissipation member in the seismic design of the overall structure. Therefore, this paper replaces the traditional reinforced concrete coupling beam of the inner tube of the shear wall with a replaceable energy-dissipation steel coupling beam, and the strength, stiffness, and stability of the replaceable steel coupling beam are designed to improve the sustainability of the structure. By changing the position of the replaceable coupling beam, the relative stiffness of the inner and outer tubes of the diagrid tube structure, and the plane form of the structure, the static elastoplastic analysis and seismic response energy analysis of different diagrid tube structures are carried out, and the influence of the replaceable coupling beam on the sustainable seismic performance of the diagrid tube structure is studied. The results show that the replaceable coupling beams have little effect on the ultimate bearing capacity of the structure, but the ductility and sustainability of the structure are significantly improved, and the whole building layout is the optimal layout scheme. The setting of replaceable coupling beams makes the diagrid tube structure show hysteretic energy-dissipation earlier under the action of large earthquakes, and the proportion of hysteretic energy-dissipation is greatly improved, which reduces the inter-story drift ratios and the damage degree of the diagrid columns under the action of large earthquakes. When the relative stiffness of the outer tube of the diagrid tube structure is small or the plane form of the structure is a regular quadrilateral, the application of replaceable coupling beams is more effective in improving the ductility and sustainability of the structure and reducing the damage to the diagrid column under large earthquakes.

A Novel Three-Dimensional Composite Isolation Bearing and Its Application to the Mitigation of Earthquakes and Traffic-Induced Vibrations

by Qiaoyun Wu, Hang Xu, Zhifeng Xu and Xuyong Chen

Sustainability 2023, 15(23), 16374; https://0-doi-org.brum.beds.ac.uk/10.3390/su152316374 - 28 Nov 2023

Abstract

Potential damage caused by earthquakes combined with reduced comfort due to traffic has become a big challenge when designing modern buildings, and base-isolation is one of the most effective solutions to such a problem. However, most isolation bearings cannot provide sufficient mitigation for both earthquakes and traffic-induced vibrations simultaneously. To this end, this research proposes a new type of three-dimensional isolation bearing for the mitigation of both earthquake effects and traffic-induced vibrations, which is composited by a thick rubber bearing, an auto-reset flat sliding bearing, and a double concave friction pendulum bearing. In this study, the analytical hysteresis model of the proposed isolation bearing was derived and experimentally validated. In addition, the fatigue performance and vertical compression performance of the proposed isolation bearing was tested and analyzed. Finally, the mitigation effect for traffic-induced vibrations of the proposed isolation bearing was validated through a field test. Full article
