Human-Structure Dynamic Interaction during Short-Distance Free Falls

Figure 9

Effects of taking into account the floor dynamics on the peak impact force experienced by a human body: a typical building floor ((a), (c), and (e)) and a raised floor ((b), (d), and (f)).

(a) = 5%, 10%, 20%, and 30%; = 3500 kg; = 10 Hz; = 1%

(b) = 5%, 10%, 20%, and 30%; = 500 kg; = 20 Hz; = 1%

(c) = 1000, 2000, 4000, and 8000 kg; = 10%; = 10 Hz; = 1%

(d) = 100, 200, 500, and 1000 kg; = 10%; = 20 Hz; = 1%

(e) = 5 Hz, 10 Hz, 20 Hz, and 40 Hz; = 10%; = 3500 kg; = 1%

(f) = 5 Hz, 10 Hz, 20 Hz, and 40 Hz; = 10%; = 500 kg; = 1%
