Abstract ：
为研究受力筋灌浆套筒连接装配式混凝土桥墩的抗震加固方法，以受力筋灌浆套筒连接装配式混凝土桥墩和灌浆套筒-预应力筋连接装配式混凝土桥墩为研究对象，设计制作了两个1/6缩尺模型，并依据二者的震害特点提出了一种采用碳纤维复合材料-外置金属耗能装置(简称CFRP-EMD)的组合加固方法。选取近断层地震波作为输入，开展了单、双向激励下模型桥墩的振动台试验，从试验现象、基本动力特性、地震响应规律等方面分析了CFRP-EMD对两类装配式混凝土桥墩的加固效果。结果表明：地震作用下两类试件的主要震损包括墩身开裂、墩底接缝开合、接缝混凝土剥落压碎等；附加预应力筋连接可提高构件刚度和自复位能力，降低墩身和接缝的损伤速率和损伤程度；采用CFRP-EMD组合加固能够显著提高震损装配式构件的刚度、抗震变形能力和耗能能力；CFRP-EMD加固后灌浆套筒-预应力筋连接装配式混凝土桥墩的塑性变形更加合理。提出的组合加固设计方法和实施原则可用于装配式混凝土桥墩抗震加固中。

Abstract ：
Multi-particle dampers (M-PD) can be potentially applied in civil engineering because of their good damping effect and wide frequency band. However, because of their complex nonlinear mechanical properties and the lack of a reasonable mechanical model, their development and application in practical engineering are limited. Therefore, without considering the accumulation of particles, an equivalent inertia single-particle mechanical model (EISM) is proposed by introducing an inerter to consider the effect of particle rolling on the damping mechanism and performance. Dynamic analyses of the EISM single degree of freedom system in the non-collision stage and the periodic motion after collision are performed based on the analytical solution. The influence of inertance on the frequency response curve of dynamic amplification factors in the no-collision stage and the analytical solution for the symmetric two-impacts-per-cycle motion are discussed in detail. Numerical simulations and experimental verification are conducted to verify the rationality of the above theoretical analysis. The results show that EISM can further clarify the nonlinear characteristics of M-PD. The inertance has a significant influence on the frequency response curve of the dynamic amplification factors as well as the boundary conditions and stability of the analytical solution of the symmetric two-impacts-per-cycle motion. The proposed EISM and the corresponding theoretical analysis in this study can theoretically support further analysis of the vibration reduction mechanism and design of M-PDs. © 2021 John Wiley & Sons, Ltd.

Abstract ：
Multi-particle dampers have a good application prospect in the field of civil engineering structures because of their good damping efficiency and wide frequency band. However, the highly complex nonlinear mechanical properties and the lack of a reasonable mechanical model limit its application and development in practical engineering. In view of this, an equivalent single-particle mechanical model with inerter was established without considering the accumulation of particles. The introduction of inerter further considered the influence of particle rolling on the damping mechanism and effect. Then, the theoretical analysis of a single-degree-of-freedom structure with a multi-particle damper was carried out. The influence of inertance on the frequency response curve of displacement in the non-collision stage and the steady-state analytical solution of periodic collision after collision were analyzed emphatically. Numerical simulation and experimental research were also carried out to verify the correctness of the theoretical analysis. The results show that the equivalent model proposed can further clarify the nonlinear characteristics of the multi-particle damper after considering the inerter. The inertia coefficient has a significant influence on the frequency response curve of the controlled structure in the non-collision stage and the analytical solution (boundary and stability) of the periodic motion after collision. The steady-state analytical solution of periodic motion provides a theoretical basis for further parameter influence analysis and for damping mechanism analysis of particle dampers.

Abstract ：
Statistic and theory based methods are mainly used for predicting earthquake input energy. Statistical energy spectrum methods need abundant time-history simulation and are lack of solid theoretical basis, while theoretical prediction methods are derived from structural dynamics with necessary assumptions, so that these methods have relatively low accuracy resulted from their assumptions. In this work the comparison of simulation and analysis showed that, due to the influence of structural transient response ignored by existing theoretical prediction methods, more than 40% errors exist in prediction of earthquake input energy for structures with low damping ratio and long period. Based on Fourier decomposition, a new theoretical method was proposed for earthquake input energy prediction considering the influence of transient response. The comparative analysis show that the proposed method significantly improves prediction accuracy of earthquake input energy. © 2021 Elsevier Ltd
