Title: Innovations by Tadaki Kawada in Suspension Bridge Engineering
Introduction
Tadaki Kawada is a notable inventor based in Musashino, Japan, recognized for his contributions to the field of suspension bridge engineering. With a total of two patents to his name, Kawada has developed innovative solutions aimed at enhancing the performance and safety of long-span suspension bridges.
Latest Patents
Kawada's latest patents include a super-long span suspension bridge designed as a countermeasure against storms. This innovative structure improves static and dynamic wind resistance performance by applying a mass to a portion of the girder. Specifically, in bridges with a center span exceeding 2,000 meters, a mass application member is installed on either side of the stiffening girder. This member can temporarily carry a predetermined amount of additional load, allowing for a mass weighing 30% or less of the girder's weight to be applied during storms. Additionally, cross stays are strategically placed to enhance stability.
Another significant patent is the temporary stiffening girder for suspension bridges. This design features a smaller dead load under normal conditions, with the capability to apply a temporary dead load as an additional mass during violent storms. This innovative structure is not only economical but also includes a passage within the stiffening girder to facilitate the movement of the temporary dead load. This feature helps control vibrations caused by strong winds, ensuring the bridge's stability during adverse weather conditions.
