本研究旨在建立一个加速度响应谱，可用于土木工程结构的振动适用性评估，如楼板和看台等受单个弹跳动态激励的结构。该谱是通过对具有可变固有频率和阻尼的单自由度系统在大量实验测量的单个弹跳载荷作用下的加速度响应的数值模拟和统计分析得出的。它的数学表达式适合于在设计实践中快速而可靠的应用，由三个方程组成，描述了实际数据中观测到的三个不同的频率区域：第一个谐振平台（2-3.5 Hz），第二个谐振平台（4-7 Hz）和下降区（7-15 Hz）。最后，通过与数值模拟和实验结果的直接对比，验证了所提出的响应谱预测方法对结构振动的预测效果。
This study is designed to develop an acceleration response spectrum that can be used in vibration serviceability assessment of civil engineering structures, such as floors and grandstands those are dynamically excited by individual bouncing. The spectrum is derived from numerical simulations and statistical analysis of acceleration responses of a single degree of freedom system with variable natural frequency and damping under a large number of experimentally measured individual bouncing loads. Its mathematical representation is fit for fast yet reliable application in design practice and is comprised of three equations that describe three distinct frequency regions observed in the actual data: the first resonant plateau (2–3.5 Hz), the second resonant plateau (4–7 Hz) and a descension region (7–15 Hz). Finally, this paper verifies the proposed response spectrum approach to predict structural vibration by direct comparison against numerical simulations and experimental results.
