Analyzing and summarizing these observed seismic damages can enhance our understanding of the impairment of communication base stations during earthquakes, providing valuable information for establishing a Bayesian network model for functionality loss.
Ke et al. proposed a method for assessing damage to mobile communication facilities during large earthquakes. The study analyzed the impact of power outages and evaluated the damage caused by ground motion to base stations using fragility curves .
In several major earthquakes, communication tower damage tends to be relatively minor, often lacking obvious damage . However, in high-intensity areas, the apex of some mountaintop base station towers might experience bending and damage, altering or detaching antenna orientations. A few towers might even collapse.
The communication tower and its antenna equipment are responsible for signal transmission and reception, and their damage directly affects the normal operation of the base station. This study mainly considers tower body damage (X 11) and antenna damage (X 12).
The seismic fragility for base stations expresses the damage state probabilities of key equipment as a function of seismic demand. Current research on the seismic vulnerability of different communication equipment is still in its infancy, primarily relying on limited seismic damage investigations and experimental research data.
For example, in areas with high PGA values, reinforcement measures such as increasing the thickness of reinforced concrete walls and installing supports or dampers can be implemented to enhance the base station's seismic resistance and reduce its seismic risk. 4.3. Functional failure causes of base station
