Title: Hajime Anzai: Innovator in Earthquake-Resistant Structures
Introduction
Hajime Anzai is a notable inventor based in Niigata, Japan. He has made significant contributions to the field of earthquake-resistant structures, holding 2 patents that focus on innovative methods for enhancing structural integrity during seismic events.
Latest Patents
Anzai's latest patents include a design analysis method for earthquake-proof reinforcement structures. This method involves selecting a member of an earthquake-proof reinforcement structure based on the allowable stress intensity ratio. It sets a ductility factor ratio that allows for deformation magnification by earthquake-proof reinforcement. The method calculates the increase in load within the plasticity range acting on the selected member, ultimately determining the corresponding allowable stress intensity ratio. When this ratio is defined as a maximum value of 1.0, it specifies the ultimate load at which the selected member collapses.
Another significant patent is the root wrapping type aseismic reinforcement construction and method for the base of a column member. This invention introduces a buffering portion between the base of the column member and a root wrapping member. This design reduces the bending moment generated on the base by external forces, thereby minimizing the bending moment transmitted to the foundation member and reducing the load borne by the foundation.
