Introduction Along with the progress of power electronic technology, and for the significant advantages in high-voltage, high power, long distance and transmission stability, High-voltage Direct Current (HVDC) transmission engineering holds an increasing proportion in the electronic network construction in China, so are the buildings of the converter stations [1].
As power electronic system is a kind of lifeline engineering, any failure or collapse damage of the electronic network structures under earthquake actions will inevitably lead to serious safety hazards and impede normal operations of the national economy[2].

In addition, modern chemical engineers are also concerned with pioneering valuable materials and related techniques - which are often essential to related fields such as nanotechnology, fuel cells and biomedical engineering.
Mechanical engineering is a discipline of engineering that applies the principles of engineering, physics and materials science for analysis, design, manufacturing, and maintenance of mechanical systems.
It is one of the oldest and broadest engineering disciplines.
It is also an important part of forensic engineering and failure analysis.
