Special Issue Information

Dear Colleagues,

Structural dynamics refers to a type of analysis that covers the behavior of a structure after exposure to dynamic excitations. Symmetry/asymmetry in structural dynamics can be considered among the most important notions in determing the behavior of a physical structure when subjected to force. In this regard, it should be expressed that the investigation of applications based on symmetry/asymmetry in the structural analysis of dynamic structures is very important in engineering applications such as submarines, rocket fuel tanks, satellite support structures, missiles, underwater toroidal pressure hull, and fusion reactor containers. It is therefore no surprise that a large number of researchers have been investigating the structural analysis of these structures under various dynamic excitations for decades.

The aim of the present Special Issue is to investigate the application of symmetry/asymmetry in the dynamic structures, which can be extremely useful in engineering and mechanical applications. For instance, symmetry analysis in structural dynamics can help researchers to identify mode localization and energy transfer mechanisms.

We solicit contributions (research and review articles) that cover a broad range of topics on applications related to symmetry/asymmetry in structural dynamics, including (but not limited to) the following areas:

  • Symmetry analysis in structural dynamics;
  • Asymmetric structures and vibration modes;
  • Utilizing asymmetry in structural dynamics to enhance structural response and stability;
  • Investigating the effects of symmetry breaking on vibration modes and modal analysis of complex structural systems;
  • Applications of symmetry/asymmetry in structural dynamics;
  • Symmetry-based design principles in structural dynamics;
  • Exploiting symmetry/asymmetry in structural dynamics to enhance the structural efficiency and load-carrying capacity;
  • Dynamic control through structural asymmetry.

This paper focuses on the seismic response of symmetrical underground subway stations to seismic waves with varying frequencies and peak ground accelerations (PGAs), essential in light of growing urban underground transit systems. A 1/40 scale station model was subjected to seismic simulations using waves from the Wenchuan and Tangshan earthquakes and an artificial wave spanning 0.1 g to 0.5 g PGAs. Shaking table tests revealed that seismic impacts divide at PGA = 0.3 g; high-frequency waves affect structures more below this threshold, while low-frequency waves have more impact above it. The columns on the third basement level responded more to seismic activity, particularly at their base. The study recommends prioritizing the seismic design of these columns during station construction, especially in earthquake-prone zones. Understanding the dynamic effects of different frequencies and amplitudes is crucial for selecting and reinforcing materials and structural designs to enhance seismic resistance. Full article
