Research Abstract |
This study was performed with the aims of elucidation of response behavior of spatial structures and development of comprehensive response control methods for natural disasters such as earthquakes or typhoon. The response behavior of spatial structures subjected to large earthquake motions or in strong wind was investigated by carrying out the vibration tests, wind tunnel tests and numerical analyses. For the response control methods, in addition to the passive response control, the active response control by feedback control and the method of searching for the forms with minimum response by treating the response control as an optimization problem were examined.
