It is well-known that a scissors structure is one of the major deployable structures, and its quick folding and expansion actions are so useful for a temporary structure. We have suggested ``Mobile Bridge'' which is applied this scissors structure to a bridge form of an emergency bridge. The rapid expansion/folding action of Mobile Bridge enables %to is useful for the scissors-type emergency bridge the saving of the transit and construction time at the disaster sites. To that end, reducing the dead weight is important because mobility or performance depends on its own weight. In this paper, we evaluated the 6N01 aluminum alloys with three - hollow section experimentally and carried out the design calculation of Mobile Bridge by using the experimental results. As the results of the design examples, we revealed the correlation among the expansion angle, length of the structural member and the number of scissors unit, and obtained the basic data for design of Mobile Bridge.
