The uncontrolled energy such as the ground motion caused by earthquakes, the hydrodynamic shock caused by floods, the thermal radiation caused by fires, and the blast wave caused by explosions may act on the hazard-affected objects in CPI sequentially or synchronously , leading to various forms of equipment failure and structural damage. The complicated and non-stationary response behavior of critical equipment in CPI subject to the coupling effects of multiple hazard-formative factors can be observed by numerical simulation. However, it is still necessary to design and carry out appropriate small-scale, large-scale, or full-scale multi-hazard coupling equipment damage experiments to cross-verify the numerical simulation results. In addition, some advanced machine learning algorithms are recommended to overcome the scarcity of reliable data sources.
