Abstract ：
金属屈服型阻尼器通常存在疲劳损伤后需要更换和不易满足大行程要求的问题,提出一种齿轮传动环向铅剪切阻尼器(GD-CSLD).基于铅材常温动态回复再结晶性能,并通过齿轮齿条配合使该阻尼器具有理论上无疲劳损伤及无位移上限的优良特征.根据核心耗能部件的构造对3个不同剪切轴截面的模型试件进行了数值模拟和试验研究,选择最优剪切轴截面方案设计加工了GD-CSLD,通过性能试验对该阻尼器的滞回性能、疲劳性能进行研究.基于有限元分析和试验结果,对该阻尼器耗能机理进行分析.结果 表明:该型阻尼器滞回性能稳定,可实现大行程加载,多次加载后基本无疲劳损伤效应;其耗能机理包含铅材屈服和侧向钢-铅摩擦两部分,且两者贡献基本相同.

Abstract ：
Based on theoretical derivation, complex modal mass participation ratio is gained, which can be applied to complex modal superposition approach for non-classical damping systems. In this paper two equivalent expressions of complex modal mass participation ratios are developed and both of them can be used to determine the reasonable mode number. In addition, the modal mass participation ratios of real and complex modes are unified according to the condition of complex modes degenerating to real modes (i.e., the real part is proportional to the imaginary part). There is no further assumption involved in the new proposed modal mass participation ratio except those have been adopted in the real modal mass participation ratio and have the same physical meanings. Thus it is easy for design engineers to master and apply. A typical isolated and response controlled buildings and a nine-story steel benchmark model with viscous dampers are taken as numerical examples, to demonstrate the significant effectiveness of the complex modal mass participation ratio to evaluate reasonable mode number. It should be noted that the mode number determined by the modal mass participation ratio to evaluate the acceleration response is smaller than that required to reach acceptable accuracy level, since the modal mass participation ratio is derived based on the base shear. © 2020, Editorial Office of Journal of Building Structures.

Abstract ：
针对适用于非经典阻尼体系的复振型叠加方法,基于理论推导,得到了评价振型贡献程度的复振型质量参与系数,并给出了两种等效的表达形式,可作为评估非经典阻尼系统所需振型数量的一种方法。同时,根据复振型退化为实振型的条件(即实部与虚部成比例关系),论证了实、复振型质量参与系数法的统一性。实、复振型质量参与系数基于相同的原理和假定,具有相同的物理意义,易于工程设计人员掌握和使用。采用典型的减隔震系统数值算例和安装黏滞阻尼器的9层钢结构Benchmark模型对复振型质量参与系数方法进行了验证,结果表明该方法能够有效估计所需振型数量。但是由于实、复振型质量参与系数法是基于基底剪力推导而得到,当用于评估加速度响...

Abstract ：
To improve the accuracy with which the non-stationary intensity characteristics of artificial acceleration-time-history curves are determined, a method of adjusting the frequency correlation between the artificial peak arrival time and amplitude spectrum is proposed. A calculation method for determining the peak arrival time to reflect the physical meaning of the phase-difference spectrum was first deduced. Subsequently, the amplitude-distribution characteristics corresponding to the peak arrival times for different durations of natural earthquakes were analyzed. In accordance with the distribution characteristics of the reference amplitude, the frequency distribution of the artificial peak arrival time was divided into four parts: the beginning, strong-earthquake, attenuation, and tail sections. By adjusting the arrival frequency of peak points for the different earthquake durations considered, the corresponding relationship between the artificial peak arrival time and amplitude spectrum was determined to be more consistent with the general law of natural earthquakes. The sample calculation described in this paper demonstrates that adjusting the frequency correspondence between the artificial peak arrival time and amplitude spectrum greatly improves the accuracy of the non-stationary intensity characteristics of artificial acceleration-time-history curves.

Abstract ：
Aiming at the design scheme for coal-fired power plant building with coal bucket dampers, an optimization method of design parameters was established and four kinds of damping structure models were designed according to the optimization method. The shock absorption effect of the damper-added structures under the action of 53 groups of ground motions was studied using the elastic time history analysis. Finally, the shock absorption effect of the structures in the elastoplastic stage under the action of the Elcentro wave was investigated. The results indicate that the four coal-fired power plant structures with coal bucket dampers have a significant reduction effect on the structure response compared with conventional structures. The reduction effect maintains a certain stability even after the structures entering into the elastoplastic stage and the story drift and the damage degree of the structures are obviously reduced. Overall, the use of coal bucket dampers in power plants, which changes the aseismic disadvantages into aseismic advantage, significantly enhances the seismic performance of structures and has good prospects for application. © 2019, Editorial Office of Journal of Vibration and Shock.

Abstract ：
为了保证人工地震波具备强度非平稳特征和频率非平稳特征,需要通过拟合方法生成频率分布特征符合要求的人工峰点到时. 天然地震波的峰点到时频率分布特征普遍存在"尾部突起"现象,因此提出利用正态分布拟合调整后的峰点到时频率分布特征的方法,并根据天然地震波的峰点到时频率分布峰值优化正态分布标准差. 选取符合不同条件的640条天然地震波为研究对象,分别利用正态分布、对数正态分布、伽马分布对峰点到时频率分布特征进行拟合研究,发现利用正态分布拟合方法生成的人工峰点到时频率分布特征最符合天然地震波的峰点到时频率分布特征.
