Explanation
Shock Transmission Unit (STU_) is a device that has less resistance to long-term movements including temperature changes, creep, and drying shrinkages, and high resistance to short-term movements like breaking forces or an earthquake. The STU has a simple structure of velocity-dependent silicone putty filled inside a cylinder, so that the STU can lock the structure against velocity loads like earthquakes, etc., dispersing horizontal load along the structure.
