ABSTRACT:
Many natural disasters cause not only
critical situations for facilities and resident’s residents’ life, but also
significant damage to economy. It is obvious that quick rescue action must be
undertaken and that there are many problems due to the occurrence of secondary
disasters at rescue worksite. Basing Based on the previous study of deployable
structures and the concept of the multi-folding micro-structures, we propose a
new type of foldable bridge in form of scissor structure called the
Mobile-bridge?. In this paper, we discuss the vehicle passing test performed on
the real-scale Mobile-bridge in order to evaluate its mechanical
characteristics and application limits. Moreover, we verified the compatibility
between the result of calculations and experiments by means of theoretical
modelling. The results show that it is sufficient to treat the load as
equivalent nodal forces applied at the joints without including the stiffness
of the deck.
