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 ：
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.

Abstract ：
Particle dampers have good performance of vibration control and noise reduction, and they have been widely studied and applied in the field of high-frequency vibration control, such as aviation and mechanical engineering. However, the vibration characteristics of civil engineering structures are usually low frequency and low amplitude, which restricts the performance of particle dampers. A new type of particle damper, namely the multiple unidirectional single-particle damper (MUSPD), is advanced based on the comparative analysis of the construction characteristics, damping performance, and damping mechanism of a single-particle damper and multiparticle damper. Based on the analysis of the damping mechanism of MUSPD and the integral consideration of the stress state of particles, the mechanical model of MUSPD is established, and an efficient numerical calculation method with variable step size is proposed. For harmonic excitation, the relationship between the optimal motion distance of a particle and other parameters is established by theoretical analysis. In addition, the optimization analysis method of MUSPD subjected to ground motions is proposed, and the rationality and accuracy are all verified. The results show that MUSPD has a better damping effect than a classical particle damper. Because the MUSPD belongs to acceleration (force)-related dampers, the energy of the controlled structure will be transferred as long as the particles collide with the controlled structure, and the frequency richness and randomness of the ground motion spectrum enhance the probability of particles colliding with the controlled structure. Moreover, the site effect has no obvious influence on the damping effect of MUSPD, and it is more suitable for middle- and low-rise structures.

Abstract ：
A double-layer tuned mass damper (DTMD) has advantages of wide damping frequency band and strong robustness. At present, there is a lack of seismic design methods for high-rise structures based on DTMDs. In this study, a DTMD parameter optimisation method was proposed, with the objective of minimising the peak displacement response of a first N-order vibration modal with a vibration mass participation factor of 85%. Then, a scale model of a high-rise structure was fabricated, along with a corresponding DTMD. Different types of excitations were chosen to clarify the dynamic responses of the model with and without the DTMD, including Site-II ground motions, long-period (LP) ground motions without pulses, and near-fault pulse-type (NFPT) ground motions. The results indicate that the dynamic responses of high-rise structures under LP and NFPT ground motions are much greater than those under Site-II ground motions. The DTMD can effectively reduce the absolute displacement response, acceleration response, and strain response at the top floor of the test model. However, the DTMD has a time delay in providing the damping effect. A smaller damping ratio between the upper TMD and the controlled structure will lead to a more significant damping effect for the DTMD.

Abstract ：
Self-pierce riveting (SPR) with high connection efficiency and automatic level is suitable for joining galvanized steel sheets in cold-formed steel structures. 51 SPR joints in galvanized steel sheet were tested to study their shear performance. The effects of sheet thickness, sheet thickness ratio, and rivet length on the failure mechanism and shear performance were investigated. And an empirical equation about the relationship of sheet thickness and rivet length was developed. This paper also analyzed the applicability for the existing calculation method of shear strength of SPR joints and the design methods of shear strength of self-drilling screw joints in some specifications, and then proposed a new calculation method of shear strength. The results showed that sheet thickness and thickness ratios were two critical factors in the shear performance and failure mechanism of SPR joints. There was an optimal rivet length for each sheet thickness, which could be calculated directly by the developed empirical equation. Compared with the existing methods, the calculation method of shear strength for galvanized steel sheet SPR joints proposed in this paper considered overall failure modes, and had superior calculation accuracy and favorable stability.

Abstract ：
The installation of energy dissipation devices on building structures can significantly reduce seismic damage. A brief review of first, second and third generation performance-based seismic design (PBSD) theories, and a comparative analysis of existing PBSD methods for energy-dissipated structure systems confirms that design methods based on force, displacement, and energy are inadequate. A more comprehensive approach is the damage-based design method, which can evaluate the seismic performance of structures. However, due to the lack of an analytical relationship between the additional equivalent damping ratio (AEDR) of dampers and the damage degree of the main structure, the current performance design method can only predict the expected damage via an iterative adjustment analysis of damper's design parameters. The authors addressed this problem by analyzing the damage mechanism of the energy-dissipated structure system's core area from the perspective of energy dissipation. It is established an analytical relationship between the AEDR and the damage index of the main structure with dampers via a damage model based on the energy difference ratio and the time-varying AEDR calculation of dampers subjected to ground motions. With this new approach to seismic vulnerability analysis, the performance design flow of the seismic structure system is based on damage control. A case study verifies the accuracy of the damage-degree based AEDR calculation. The proposed damage-based method effectively controls the damage degree of the main structure to the expected damage target. This method is compatible with the displacement-based design method, and which also enriches the research contents of structural seismic design and damage analysis in the third generation PBSD.
