Safety Control of Urban Space
To develop a methodology for safety control of urban space and to create advanced living environments that are safe and comfortable, we study risk evaluation methods of populated regions subjected to strong ground motions and reliable design methods of urban space and built environments. The main research topics are as follows: 1) Evaluation of seismic input to structures and urban facilities based on the regional characteristics of source, path, and sites and quantification of seismic risks. 2) Establishment of methods for the seismic reliability analysis and reliability-based design of buildings, considering uncertainty in structural parameters and seismic input motions. 3) Development of structural health monitoring and control systems, including the damage evaluation of structures. 4) Development and promotion of new seismic reinforcement methods for buildings, especially traditional wooden houses.
