| Summary: | Prefabricated structures have gained wider application. However, there is little research on the vibration response of prefabricated frame structures in subway environments. Prolonged metro-induced vibrations may severely degrade human comfort levels for nearby residents, interfere with the operation of precision instruments, and accelerate structural fatigue damage. Consequently, it is imperative to investigate the vibration response patterns of prefabricated frame structures under metro operational conditions. Structural vibration responses demonstrated greater sensitivity to column sections and slab thickness than beam dimensions when using semirigid connections, though marginal effects emerged with parameter increases. Enhanced vibration thresholds require supplementary vibration reduction measures. Increasing total spans proved more effective in vibration reduction than adding stories, with vibration transmission exhibiting notable edge effects. Related research can provide reference for the structural design of prefabricated frame structures around the subway. |
