Anti impact and noise reduction single seam expansion device, three-dimensional displacement and isolation modulus expansion device with GO system or GU system.

Option A: Increase the strength and stiffness of the structure, Option B: Isolate and absorb energy for conversion. Option A (traditional "seismic" concept): requires a large amount of reinforcement such as steel bars and concrete. When the energy level exceeds the design level, the building and its internal properties will be damaged; Human life is threatened or dies. Plan B (modern "shock absorption" concept): The structure of the building is streamlined, and devices such as seismic isolation expansion joints, supports, and dampers isolate and absorb enormous energy, ensuring the safety of the building, its internal properties, and precious lives.

No, in a project, the structural designer needs to analyze and design structural protection and isolation devices from the perspective of the overall structure, tailor them and continuously optimize them in order to save costs to the greatest extent possible.
