Vibration serviceability check

Topic:Vibration serviceability check
Including following
1) What vibration is;
2)footfall induced vibration( How footfall going to induced vibration,e.g person walk cross the bridge apply dynamic force and structure response dynamically)

3)human perception( how we feel the vibration, how it doesn't disturb the human)
explain the natural frequency blow 10Hz of the footbridge leads to resonant response calculation but if its above 10Hz using the impulsive response calculation….

mainly is to paraphrase the guide(unloaded docement) up to around page 30 to cover all above requirment and there might be some other important points needs to explain which related to vibration serviceability check for a structure( footbridge)
