Special Issue Information

Dear Colleagues,

The seismic retrofitting and performance evaluation of transportation infrastructure remain critical concerns, particularly in regions prone to seismic activity. Recent earthquakes have underscored the vulnerabilities of existing structures, emphasizing the pressing need for advancements in engineering practices and materials to enhance seismic resistance.

This Special Issue aims to showcase the latest expertise and knowledge in this field, welcoming original contributions such as research papers, case studies and reviews. Both existing and new transportation infrastructure are of equal importance, and the focus extends to a wide spectrum of research activities. The scope of this Special Issue encompasses experimental setups for assessing seismic performance, monitoring techniques for early awareness and prevention measures, numerical analysis of structures, exploration of behavior factors, advanced nonlinear simulations, fragility analysis and case studies of new, existing and retrofitted transportation infrastructure.

Furthermore, the issue seeks to explore innovative technologies such as base isolation and energy dissipation elements, offering a platform for researchers to present their findings and insights. By gathering contributions on these vital topics, we aim to advance the understanding and implementation of seismic retrofitting and performance evaluation, ultimately contributing to the creation of safer built environments in seismic-prone regions. Potential topics include, but are not limited to:

  • Seismic retrofitting;
  • Transportation infrastructure;
  • Performance evaluation;
  • Seismic resistance;
  • Seismic activity;
  • Engineering practices;
  • Structural assessment;
  • Retrofitting technologies.

With the increasing construction of undersea tunnels in seismic-prone areas, accurately assessing their response to seismic conditions is crucial. To grasp the dynamic response of undersea tunnel structures to seismic waves, the shaking table test of water–sea–sea submarine tunnel is designed and carried out based on the methods of orthogonal design and fuzzy method. A comprehensive time-domain model is developed to capture the nonlinear dynamic interaction of ocean engineering structures, taking into account seismic waves, seawater, and saturated soil. The research results show that as the burial depth at each measurement point of the submarine tunnel increases, the acceleration response decreases and the horizontal displacement relative to the seabed surface increases. Comparing test and finite element simulation results reveals that under seismic loading, the strain distribution pattern of the tunnel section is mainly in the arch shoulder, waist, and foot with larger strain peaks, whereas the strain peaks at the arch top and the superelevation arch are smaller. Simultaneously, doubling the water pressure induces a slight increase in the overall strain response peak of the tunnel, with an indistinct relative displacement change rule. When a vertically polarized shear wave (SV wave) is vertically incident, different dynamic response indices will have different trends with the change in water level. This study may provide a reference for shaking table tests for saturated soil–submarine tunnels at complex sites. Full article
