A sequential stiffness support is provided for a bearing assembly to improve vibration characteristics of a gas turbine engine and to provide a variable structural stiffness to the support to minimize unbalance load transmissibility. In one embodiment, and by way of example only, the sequential stiffness support includes an inner ring, an outer ring, and means for coupling the inner ring and the outer ring. The sequential stiffness support is configured to provide a first stiffness support at a first engine speed and a second stiffness support at speeds greater than the first engine speed. Methods of manufacturing the sequential stiffness support are also provided.
