【摘要】 本文假定人群行走工况下楼板上各点的功率谱密度函数相同,应用随机振动理论,推导了楼板振动响应的计算公式。本文推导的公式可以根据不同的分位点,确定等效同步人数;不仅适用于单向人行桥,也适用于双向大跨楼板;给出了等效同步人数的简化算法。更多还原

【Abstract】 In this paper,it is assumed that anywhere’s PSD on the floor are equal,several formulas to calculate floor vibration response are derived uses random vibration theory. The equivalent number of synchronous people under different fractile can be calculated. The formulas can be used for either one-way slab or two-way slab. The paper also gives a simplified formula to calculate equivalent number of synchronous people.更多还原
