| Outline of Final Research Achievements |
For the functional maintenance of buildings that accommodate equipment with vibration control devices, new control methods and design procedures were developed. 1) A cooperative control method for buildings and equipment was constructed and its validity was confirmed through simulation analysis and shaking table tests of a data center model. 2) A low-computational-load procedure of control design using a seismic hazard curve and a building fragility curve was formulated to minimize the function failure probability. 3) A failure compensation method was developed using a reliability parameter and a linear quadratic Gaussian control and its validity was confirmed through simulation analysis and shaking table tests. 4) A response spectrum method was expanded to estimate the maximum absolute acceleration response and the maximum control force of a system with overdamped modes. 5) An optimal control method considering the damping characteristics of semi-active dampers was formulated.
