- Abstract:
- 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.
