【Abstract】 A new concept of generalized flexibility is introduced based on the platform response spectrum for identifying the platform damaged in different positions and changed in deck mass as well as the foundation relaxation. The tendency of the change of the generalized flexibility is shown in three cases. A series of valuable conclusions are obtained. It provides an important basis in order to develop the structural vibration monitoring technology of offshore jacket platforms.更多还原
