Title: Innovations by Tadashi Nasu in Seismic Response Control Systems
Introduction
Tadashi Nasu is a prominent inventor based in Tokyo, Japan. He has made significant contributions to the field of structural engineering, particularly in the development of active seismic response control systems. With a total of 2 patents, his work focuses on enhancing the safety and stability of structures during seismic events.
Latest Patents
Tadashi Nasu's latest patents include an active seismic response control system for use in structures. This innovative system features a variable damping device that is strategically placed between posts, beams, and braces of a structure. The system reduces the response of the frame by controlling the variable damping device during earthquakes or strong winds, thereby providing a damping force to the frame. The optimal damping force is determined by a computer based on sensor information, allowing for precise control of the damping coefficient.
Another notable patent is the variable damping and stiffness structure. This invention incorporates a variable damping device that connects posts, beams, and braces, or serves as variable stiffness elements. The system is designed to assess both the unreasonance and damping properties of the structure using computer analysis of sensor data. This allows for effective control of the variable damping device, ultimately reducing the structural response to disturbances such as earthquakes and wind.
