Abstract

Many natural disasters can cause not only a critical situation in local resident’s lives and facilities but also significant damage to the economy. Although we have to undertake quick rescue actions for these damages, there are many recovery problems, due to the occurrence of secondary disasters at each rescue worksite. Looking at previous studies of deployable structures and the control regulation of the multi-folding micro-structure, we propose a new type of foldable bridge, with a scissors structure called the Mobile BridgeTM. In this paper we discuss vehicles passing a test on a real-scaled Mobile Bridge, so as to evaluate its mechanical characteristics and application limits. Moreover, we verify the compatibility amongst the results of the analysis, the calculations and the experimental values by means of a theoretical approach and method. From these results, if design of Mobile Bridge is simplified, we understood that it is sufficient to treat the load as equivalent nodal force applying the pins without the stiffness of the deck.. Keywords: Mobile BridgeTM, scissors type of emergency bridge, aluminium alloy materials, vehicle loading test.
