Scissoring Origami Inspired Deployable Bridge for a Disaster

In recent years, natural disasters such as earthquakes, floods and tsunamis have caused widespread social damages. For example, many bridges were damaged by a typhoon in 2016 in Hokkaido area in Figure 1(a). We need to develop a new rescue structure to survive these disasters. (I.Ario, M. Nakazawa et. al. 2013) We have to consider how to rebuild damaged infrastructures and how to build a new type of rescue system. Therefore, we suggest a new type of emergency bridge, Mobile Bridge(MB), with a scissors structure that enables it to be temporarily constructed quickly as shown in Figure 1(b) (I.Ario, Nakazawa, M.Tanaka, Y.Tanikura, and Ono, S. 2013). In this paper, we will explain dynamically the calculation method of MB.
