“…The intelligent adjustment function of the active vibration control system enables it to adapt to different vibration conditions, further enhancing the stability and safety of the system. Through data analysis, we validated the effectiveness of active vibration control systems in reducing structural vibration caused by earthquakes and wind vibrations, and demonstrated their intelligent and adaptive adjustment characteristics [5] . The application of this technology will provide higher safety and stability for high-rise buildings, thereby enhancing people's confidence and comfort in the building.…”

Vibration characteristics and control strategies are crucial for system performance and structural safety. Through the research of vibration mechanics analysis, control strategy, application and new trend, we find that Multiphysics simulation coupling vibration analysis and control algorithm based on artificial intelligence are new research directions. Vibration analysis and control still face challenges in complex system models and parameter determination. Future research should focus on addressing these issues and exploring new vibration control applications. Through continuous research and innovation, we will deepen our understanding of vibration behavior, drive technological development, and provide effective solutions. This will have a positive impact in various fields, creating a safer, more reliable, and comfortable living environment for us, and promoting the advancement of science and technology.

“…At the same time, the polymer can advance the bond performance between fiber and matrix effectively, thus further taking advantage of the fiber in concrete for composite modification effect (Zou and Sneed 2020;Mohammadyan et al 2021). But at present, there are still few studies on the impact resistance of fiber polymer composite modified concrete and the mechanism of fiber promoting the performance of polymer reinforced concrete as well as relevant reports (Guo et al 2020;Valarezo et al 2021;Xiong et al 2021b).…”

To explore the dynamic compressive mechanical properties of carbon fiber modified polymer reinforced concrete (CFMPRC), the 100 mm diameter SHPB (Split Hopkinson Pressure Bar) test system was used to carry out impact compression tests of CFMPRC with different carbon fiber volume content (0.1%, 0.2%, 0.3% and 0.4%). The dynamic stress-strain curves and fracture morphology of CFMPRC under different strain rates (37.7 s -1 to 132.2 s -1 ) were obtained, and the effects of strain rate and carbon fiber content on dynamic compressive strength, deformation and toughness of CFMPRC were analyzed. The results show that the dynamic compressive strength, deformation and toughness of CFMPRC have obvious strain rate strengthening effect and carbon fiber strengthening effect. The dynamic compressive strength, dynamic increase factor (DIF), dynamic peak strain and impact toughness of CFMPRC increase with strain rate gradually. The dynamic compressive mechanical properties of polymer reinforced concrete are improved by adding carbon fiber, and the optimal carbon fiber content is 0.2%. When carbon fiber content is 0.2%, the strain rate sensitivity of CFMPRC is the strongest, and the increase of strength is the maximum. Carbon fiber can bridge the internal cracks of concrete, and shows the co-modification effect with polymer. Polymer can enhance the carbon fiber/concrete matrix interface, which makes carbon fiber exert its effect more effectively.

“…Dynamic loads, such as earthquakes and winds, cause vibrations in the building structure, leading to safety and serviceability problems. The damage caused by vibrations can be mitigated by improving the damping performance of the structure (Liang et al, 2021;Tandazo et al, 2021). Installing vibration-damping devices can improve the damping performance and seismic resistance; however, such devices involve complex construction and high costs.…”
