Research on Self-centering Aseismic Device Based on Disc Springs

Earthquake resilient structure can restore the function of the structure which does not need to repair or in the partial use of a small repair after an earthquake by the application of rocking wall, self-centering, replaceable and additional energy dissipation devices, and other technologies. Adding a self-centering device to the structure and designing it to remain elastic at a certain earthquake level can restore the structure to its original position after an earthquake. In this paper, a disc spring self-centering device suitable for rocking wall structure is developed from the aspects of material properties, conceptual design, and structural design to mechanical properties test research, to achieve a more efficient shock-proof structure with resilient functions.
