## 7 Conclusions  
This study develops a new self-centering precast concrete (SCPC) frame with hysteretic dampers. The configuration and working principles of beam-column connections are illustrated. A prototype structure is modelled and the elastoplastic dynamic responses at the DBE and MCE levels are studied. IDA and seismic fragility analysis are also carried out. In addition, the elastoplastic dynamic responses of the RC structure and the traditional SCPC structure are also studied. From the aforementioned research, the main conclusions are summarized:  
1. The novel SCPC frame can satisfy the seismic target under near-fault earthquake waves. The peak and residual inter-story drift ratios all achieve the desirable demands at the DBE and MCE levels. The maximum inter-story shear forces indicate the novel frame can undertake more load due to the large stiffness. The maximum connection relative rotations are minimal and PT forces are all below the yielding tendon force at the MCE level to maintain the self-recovering characteristic. Besides, the beam end \(M\)- \(\theta_{r}\) relation curves of the novel joint are stable and display a typical double-flag shape.
2. The results of IDA indicate the peak and residual inter-story drift ratios both nonlinearly increase approximately with the increasing intensity under near-fault earthquake waves. The dispersion degree of the peak residual inter-story drift ratios is significantly higher than that of the peak inter-story ratios and the dispersion increases with increasing intensity levels.
3. The fragility curves for the seismic limit state from IO to RE become smooth and move significantly toward the right, which means under the same \(S_{a}\) (T\({}_{1}\)) the exceeding probabilities of the corresponding \(\theta_{max}\) and \(\theta_{r,max}\) drop obviously. Based on the fragility analysis and seismic hazard analysis, the 50-year exceeding probabilities can be obtained and satisfy the seismic design objective.
4. The peak inter-story drift ratios of the traditional SCPC frame are the largest of the three frames under near-fault earthquake waves loading. The peak residual inter-story drift ratios and the peak inter-story shear forces of the RC frame are the largest; the peak residual inter-story drift ratios of two SCPC frames are minimal. The maximum connection rotations and PT tendons forces of the traditional SCPC frame are significantly larger than those of the novel SCPC frame. The results show that the SCPC frame with hysteretic dampers has great seismic behavior, energy consumption and self-recovering capacities under near-fault earthquake waves loading.
