We measured human-induced walking vibrations in an over-road hospital connecting-bridge. When walked upon at a fixed frequency by 4 people, the passage had a livability equivalent to the performance required of a typical residential building. Even when walked upon with 12 people, the performance was such that the impact on the habitability of patient room is small. In addition, the dominant frequency and damping constants were extracted from the Fourier spectrum of recorded vibrations. In the vertical direction, the natural frequency and the damping constant were estimated to be 9 Hz and 3.26% respectively.
