“…In recent years, a certain number of researchers paid attention to the pontoon floating bridge. S. Fu and W. Cui presented the dynamic analysis of floating bridges [3]. Besides, Hirono et al [4] introduced a new study on measurement system for positional displacement of floating units for pontoon bridges.…”

“…Connections are very important in determining the displacement response of ribbon pontoon floating bridges and may be either rigid-or hinge-connected. The specific connection type determines the response characteristics of the bridge such as natural frequency of vibration as well as the amplitude of vibration (Fu & Cui, 2012).…”
