Abstract ：
The accuracy of bridge performance monitoring and evaluation is easily affected by unfavorable factors such as vehicle coupling and test noise. In order to accurately evaluate the dynamic response and health monitoring threshold of the bridge under different operating conditions, a time-varying dynamic vehicle group model including the main uniform mass and the coupling mass was established, and the influence of road roughness was considered in the coupling equation. A bridge monitoring strategy considering signal noise ratio and vehicle-bridge interaction was proposed, and the effectiveness of the monitoring strategy was verified by taking a simple supported beam as an example. The results showed that the proposed time-varying dynamic vehicle group model could accurately consider the influence of road roughness and estimate the threshold of health monitoring, and the proposed bridge monitoring strategy could filter out a large amount of low signal-to-noise ratio or meaningless data, thus saving computing resources and realizing the lightweight safety monitoring of bridges.

Abstract ：
Although the tuned mass damper (TMD) is characterized by simple construction, a definite damping mechanism, and a strong damping effect, a narrow damping frequency band, a detuning effect, and large occupied space limit its application in practical engineering. Particle dampers have the advantages of damping frequency bandwidth and small space, but the damping effect is unsatisfactory. Therefore, a new combined damping system (CTP) containing a TMD and a multiple unidirectional single-particle damper (MUSPD) was developed. A series of shaking table tests for a controlled and uncontrolled structure were conducted to investigate the performance of the system, and the damping effects of a TMD, MUSPD and CTP subjected to harmonic excitation, normal ground motions, rock ground motions, and soft ground motions were compared and analyzed. Finally, a mechanical model of the CTP and corresponding numerical simulation method were developed based on its damping mechanism. The results indicate that a CTP can effectively integrate the advantages of a TMD and MUSPD, and exhibits a better damping effect, wider damping frequency band, and stronger robustness. The shaking table test demonstrates the rationality and feasibility of a simulation method for a CTP.

Abstract ：
传统地震动力放大系数谱是根据地震动最大加速度和结构最大加速度而确定的,没有充分虑及时域非平稳性。通过比较不同周期结构最大反应出现时刻和地震动峰值出现时刻,验证极大峰值对结构反应同样有重要的作用。提出考虑若干极大峰值作用的等效动力放大系数谱的概念,计算不同场地类型下的统计谱并验证其保守性。鉴于考虑频域非平稳性的动力放大系数标准差谱的合理性,计算相关统计谱并确认其在长周期段谱值较高。综合考虑传统谱、等效谱和标准差谱的特点,基于三种谱外包络提出具有足够的保守性的广义动力放大系数谱的概念。建立广义动力放大系数谱与传统谱的比值拟合公式。通过算例验证按广义动力放大系数谱进行结构抗震设计或验算具有更高的安全...

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 ：
The performance design for traditional steel rigid connection cannot fulfill the desired seismic requirements. Though beam column connection with weaken beam end can approximately realize the concept about "strong column-weak beam", the local buckling and the distortion buckling in the weaken zone and the total lateral damage maybe occur in rare earthquake and the capacity is not enough. The replacement connection with low-yield-point steel (LYPS) is proposed base on the idea of resilient structure, and its weakened parts in the flange slab and web plate are filled with LYPS. During earthquake, the LYPS primarily yields and fully dissipates energy. The damage of the main parts in the connection is minor and the LYPS can be replaced after the earthquake. According to the insufficiency of the traditional damage models, the damage model based on differential ratio of elastic plastic dissipated energy is proposed. Low cycle loading experimental research is carried out on three kinds of beam-column connections, which involve the classic connection, the beam end weaken connection and the replacement connection. Comprehensive assessments of damping performance are proposed through a variety of performance evaluation parameters. It is approved that the replacement connection has much more excellent bearing capacity, ductility and energy consumption ability. In addition, the proposed energy damage index can represent damage evolution process and damage law. Copyright (C) 2021 by The Hong Kong Institute of Steel Construction. All rights reserved.
