为研究人行激励下大跨度楼盖结构的舒适度问题,对目前比较流行的压型钢板-混凝土组合楼盖体系进行有限元建模,在此基础上进行瞬态振动的分析,将得到的结果与美国规范AISC11的计算结果和标准进行对比。结果表明:AISC11计算方法对人行激励的简化并不合理,造成峰值加速度与实际误差较大,偏于不舒适;人行激励模型考虑了多阶简谐激励的作用和人行激励作用位置的变化以及人与楼盖相互作用的过程,更贴近实际。

To study the problem of serviceability for long-span floor structures, a transient vibration analysis on the profiled steel sheetingconcrete composite floor system was made using finite element modeling method, then the results were compared with the computational and standard values of American code AISC11. The results show that the simplified method for humaninduced excitation of AISC11 is not reasonable, and the peak acceleration is very different from the real value, which is uncomfortable. Humaninduced excitation model which considers multi-order harmonic excitation effect and pedestrian excitation position change, as well as the process of interaction between human and floor, is closer to the actual.
