Summary

Disaster prevention and mitigation for engineering structures is an important research field, which involves formation mechanisms, dynamic responses, collapse analyses, disaster prevention and mitigation strategies, etc. The research of natural disasters, which include the earthquake, landslide, falling rocks, and debris flow, can avoid catastrophic damage and reduce the vibration and noise of engineering structures, bringing more comfort and convenience to human life.

Computer modelling has been rapidly evolved over the past few decades to simulate actual geologic conditions and engineering circumstances. At present, considering the local geologic hazards related to the project decision and risk analysis, which include but not limited to the water inrush, rockburst, and frozen soil, the application of the most accurate modelling method has received significant attention from the researchers in disaster prevention and mitigation.

The main purpose of the proposed special issue is to explore and share the most recent progress and novel trends in computer modeling in disaster prevention and mitigation for engineering structures. Herein, original articles and review papers addressing innovative development in computer modelling are valuable scientific contributions. Moreover, research papers summarizing state of the art are also welcomed.

  • Dynamic Performance of Straddle Monorail Curved Girder Bridge
  • Abstract In this work, a monorail vehicle-bridge coupling (VBC) model capable of accurately considering curve alignment and superelevation is established based on curvilinear moving coordinate system, to study the VBC vibration of straddle monorail curved girder bridge and the relevant factors influencing VBC. While taking Chongqing Jiao Xin line as an example, the VBC program is compiled using Fortran, where the reliability of algorithm and program is verified by the results of Chongqing monorail test. Moreover, the effects of curve radius, vehicle speed, and track irregularity on the corresponding vehicle and bridge vibrations are compared and analyzed. It is observed that… More

  • Study of Temperature Field and Structure Optimization for Runways in Permafrost Regions
  • Abstract Pavement construction in permafrost regions is complicated by the fact that the permafrost properties are influenced by the temperature and are extremely unstable. The numerical model for runway structures in permafrost regions is applied to analyze the time–space characteristics of the temperature field and the depth of the frozen layer. The influence of the installation layer is studied to enable structural optimization of the runway. Numerical results show that the temperature stabilization depth, low- and high-temperature interlayer response ranges, and maximum depth of the frozen layer are greater in runway engineering than in highway and railway engineering. The time history… More
