Evaluating Serviceability Limit State in a Long-span Skating Stadium Through Natural Frequency Analysis

This study investigated the application of vibration analysis to ensure user safety and establish an efficient management plan for the future utilization of sports facilities. The first natural frequency of the facility was documented at 3.2 Hz, while the second and third frequencies were measured at 3.56 Hz and 4.22 Hz, respectively. Experts posit that amplification is probable when the natural frequency aligns with the second and third modes. Resonance manifested at 1.8 Hz and 2.1 Hz dynamic activities within the anticipated frequency range, resulting in notable amplitude enhancements. Therefore, Constraining rhythmic actions that may elicit repetitive movements when using sports facilities is imperative to uphold serviceability and safety standards.
