| Abstract: | The vibration serviceability of long-span floors in space structures is studied.A finite element model of a human-floor coupled system is established.Then the dynamic characteristics are studied by theoretical analysis and finite element calculation.The influence of constraint conditions of floors,architectural surface and distribution of pedestrian loads for free vibration characteristics of floors are investigated.Taking long-span railway station as a project background,the research of vertical vibration ... |
