The energy dissipaters provide the structure or facilities with large amounts of damping which will dissipate most vibration energy from earthquake or wind previous to the structural response reaching the limitation (damaging the buildings or loosing the performance function of facilities), then ensure the structure or facilities to be no any damage or to keep the normal performance function during earthquake or strong wind. The shaking table testing of large models with energy dissipaters shown that, the seismic response of structure with energy dissipaters is decreased 20–40% comparing the structure without energy dissipaters.

An earthquake-resilient precast shear wall was proposed in this paper, where bolt-plate connector was used as energy dissipator. The seismic performance of the proposed ERPSW was analyzed with comparison with cast-in-situ shear wall and the earthquake resilience was verified based on the study of mechanical behavior of ERPSWR. According to the experimental research, some results could be summarized as following:
