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 ：
The traditional metal yield dampers such as buckling-restrained brace are designed only for strong earthquakes. Under small earthquake, it is difficult to dissipate the energy for common single-stage yield damper. In addition, it is difficult to observe its damage state after earthquake and inconvenient to replace the energy dissipation components separately. Therefore, a new metal sleeve damper which can dissipate the energy under all levels of earthquakes is proposed in this study. Due to the different yield displacements of the energy dissipation strips with different aspect ratios, the damper has multi-stage yield characteristics. Considering the stiffness degradation effect from the semi-rigid joints on both sides of the strips, the mechanical performance parameters of the damper are derived. The quasi-static experiment of the damper is carried out. Finite element method (FEM) is utilized to simulate the performance of the damper. At last, the damping effects of the multi-stage yield damper and common single-stage yield damper are compared. The results indicate that the accuracies of the mechanical performance parameters computation formulas are high. The energy dissipation performance of the multi-stage yield damper is excellent. The correctness of the finite element (FE) modeling method is verified. The seismic performance of the RC frame with the multi-stage yield damper is improved significantly under all levels of earthquakes. Comparing with the single-stage yield damper, the multi-stage yield damper is more effective in the vibration control of the reinforced concrete (RC) frame.

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...

本发明公开了可半主动调控阻尼性态的方斗型调谐液体阻尼器，包括方斗型水箱、可抽插隔板、初始双层隔板、隔板固定装置、浮板、浮板固定装置、隔板半主动控制装置。水箱的形态是方斗型，并在水箱中加入可改变孔洞大小的隔板，提高TLD系统阻尼比，增加液体能量耗散，同时通过半主动控制使隔板进行前后左右多方向移动，使TLD的调谐频率在受控振型的频带范围内与外干扰频率一致，这样TLD始终能提供最大的减振力。在水箱水面施加分布式浮板，结构发生振动时，分布式浮板能很好地抑制水箱中液体过度晃荡及波浪破碎情况，使得整个阻尼器的行为呈现线性，最终实现多方位调谐液体减振。本发明属于土木工程抗风、抗震和耗能减震技术领域。
