Abstract ：
颗粒阻尼技术因减振效果好、作用频带宽等优点使其在土木工程领域中具有良好的应用前景,然而因其具有高度复杂的非线性力学特性,并缺少合理的力学模型,限制了其在实际工程中的应用和发展。鉴于此,以土木工程应用为背景,在不考虑阻尼颗粒发生堆积的前提下,通过引入惯容器来考虑颗粒群滚动对阻尼器减振机理及减振效果影响,建立了考虑惯容的多颗粒阻尼器等效单颗粒力学模型;结合颗粒运动状态,分别进行了未碰撞时及碰撞发生后多颗粒阻尼器单自由度结构的响应分析,重点探讨了惯容系数对未碰撞时动力放大系数频响曲线及碰撞发生后周期2次碰撞稳态解析解的影响规律,并采用数值仿真和试验方法进行验证。结果表明,考虑惯容属性后等效模型能够进...

Abstract ：
To establish an anti-seismic reinforcement method (ASRM) for fabricated concrete piers based on carbon fibre reinforced polymer (CFRP) and polyethylene terephthalate (PET) materials, two 1/6-scale prefabricated piers with grouted sleeve connections (SFPs) and grouted sleeve prestressing tendon composite connections (SSFPs) were designed and manufactured. Shaking table tests were carried out for the model piers. Then, an ASRM using CFRP/PET with anti-sway external metallic dissipaters (AS-EMD) was proposed. The design and implementation methods of the CFRP-AS-EMD and PET-AS-EMD were established. Under the same excitation, shaking table tests of the SFPs repaired with the CFRP-AS-EMD and the SSFPs repaired with PET-AS-EMD were conducted. And finite element analysis (FEA) verification of the reinforcement effect was also carried out. The results showed that the initial seismic damage of the SFPs and SSFPs included pier body cracking, concrete spalling or crushing, and seam cracking at the bottom of the pier. The CFRP-AS-EMD and PET-AS-EMD can evidently decrease the horizontal displacement of the specimens, demonstrate good anti-sway capacity, provide a certain energy consumption capacity, and effectively improve the ductility of the reinforced pier specimens.

Abstract ：
The seismic performance and design method of fabricated concrete bridge piers limit their applications in complex and harsh environments. In this study, a continuous bridge pier in an 8-degree seismic fortification intensity area was considered as a prototype. Two 1/3-scale models were designed and manufactured. The specimens were connected via a grouted sleeve connections (SFP) and a grouted sleeve prestressing tendon composite connections (SSFP), respectively. Moreover, a cast-in-place 1/3-scale model (reinforcement concrete pier, RCP) was designed as a comparison specimen. Quasi-static experiments were performed on these three specimens. The seismic performance of the specimens was analysed according to the failure phenomena, bearing capacity, displacement ductility, stiffness, energy-dissipation capacity, and residual deformation. On these basis, a bearing-capacity estimation method for SFP (including SSFP) was developed and validated. The results indicated that the damage to the SFP and SSFP mainly accumulated along the top and bottom of the sleeves. The plastic hinge area of the SFP and SSFP moved up or down. Thus, the damage to the SFP and SSFP was concentrated at the joints. Cracks first occurred at the seam of the two fabricated specimens when the loading drift was relatively small. Then, the concrete at the loading edge of the joints was crushed. Furthermore, the longitudinal bars yielded and broke. Finally, the specimens failed. Compared with the RCP, the SFP and the SSFP had larger yield and ultimate displacements. The bearing capacities of the RCP and the SFP were similar. However, the bearing capacity of the SSFP was significantly higher. The bearing capacities of the SFP and SSFP did not decrease significantly before the specimens failed. Compared with the RCP, the SFP had a lower initial stiffness, a lower stiffness degradation rate, similar displacement ductility, smaller residual displacement, and less cumulative energy dissipation. The SSFP was better than the SFP with regard to the displacement ductility, initial stiffness, and cumulative energy dissipation. Thus, the SFP and SSFP can satisfy the seismic requirements of high-intensity areas. The proposed bearing-capacity estimation method can be used for the seismic design and evaluation of SFPs and SSFPs.
