An experimental study on the design method of a real-sized Mobile Bridge for a moving vehicle

Abstract

Many natural disasters cause not only critical situations for facilities and resident's 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 on the previous study of deployable structures and the concept of the multi-folding microstructures, we propose a new type of foldable bridge in form of scissor structure called the Mobile Bridge TM . 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.

Experimental Study on Static Performance of Deployable Bridge Based on Cable‐Strengthened Scissor Structures

“…In recent years, Yuki Chikahiro and Ichiro Ario et al have been engaged in the research and development of deployable bridges based on scissor structures and conducted a series of theoretical research, numerical simulation, and light vehicle load tests of full-scale bridges. According to the previous research, additional reinforcement members have been proposed to improve the load-bearing capacity of the bridge under static and dynamic loads [21][22][23][24][25].…”

Design and Analysis of Collapsible Scissor Bridge

“…However, this suggestion might not be the best solution to this problem in accessing remote areas. In conjunction to that, Research team at Hiroshima University had successfully developed and tested a folding bridge which is inspired by Japanese traditional origami [3]. The bridge is intended to be deployed during chaotic situations.…”
