Experimental Investigation into Seismic Response of Superelastic Tendon Restrained Rocking Structures
Rocking isolation protects a structure or structural member in earthquakes by reducing internal forces and extending response periods through uplifting at the rocking interface. The vulnerability of overturning in earthquakes makes it difficult to apply to structures without additional support in the lateral direction. Superelastic alloy tendon restraints are ideal for rocking structures because of their excellent recoverable deformation capacity. It allows the structure to have a sufficient rotation for reducing internal forces while greatly reducing the risk of overturning. This paper reported shaking table tests of a superelastic tendon restrained shear frame and a building model. In both tests, it was demonstrated that a balance between reducing seismic internal forces and preventing overturning was achieved for structures with superelastic tendon restraints. Based on the experimental results, the theoretical model of the restrained rocking structure was validated. The study provides a technical approach to the design of rocking structures such as high-rise modular buildings.
