A typical megaframe structure has a high lateral stiffness and is excellent for high-rise structures.
However, this high stiffness can lead to poor seismic response of a structure.
Seismic isolation technology is a mature and cheap vibration control method that is used for vibration reduction in megaframes.
This paper introduces a megaframe structure based on substructure combined isolation.
The structure consists of two parts.
The main body is a megaframe, and the substructure is the subframe with the combined isolation layer arranged at the bottom of the subframe.
The seismic performance of this structure system was evaluated by performing shaking table tests of two megaframe model structures.
The responses of the deformation, acceleration, and shear of the structure were measured.
The dynamic behaviors of the structure with or without the combined isolation layer when exposed to single and bidirectional near-fault and far-fault ground motions with different peak values were investigated.
The results showed that the combined isolation layer can reduce the bidirectional seismic response of the main frame and subframe.
The acceleration, base shear, and displacement responses had similar vibration reduction trends for the two model structures, and the structural responses under bidirectional earthquake were generally greater than that under a single directional earthquake.
The near-fault pulse effect increased the seismic response of the structure.
The increase of the predominant period of ground motion also increased the seismic response of the structure.
