Natural disasters such as flood, earthquakes and volcanic eruptions have always been a serious issue that threatens human lives and caused massive structural damage. Structures such as bridges that links between two areas being destroyed, disaster rescue operations will become more difficult and delayed. This situation leads to research and development of emergency deployable bridges in terms of its effectiveness in disaster rescue operations while optimizing the overall strength and ratio of weight-toloading capacity. This paper focuses on redesigning an emergency deployable bridge with stress analysis and thermal analysis. The modeling design of emergency deployable bridge tested by using 4x4 vehicle by using SolidWorks. By using Kutzbach equation, its help the design to meet the targeted degree of freedom. There is five major part like deck, pin, cross shaft and deck shaft involve in the structure and A36 structural steel being used in the simulation. Simulation results show 7.75% decrease on maximum von misses stress and 8.50% improvement on the Factor of Safety. 

Chikahiro et al [4] designed a kind of expandable mobile bridge mechanism based on the scissors unit, which is compact in size and convenient for transportation in the undeployed state, and has the characteristics of rapid deployment. Zhao et al [5] studied the large-scale folding mechanism constructed by the scissors unit by using the screw theory, and applied it to the over-constrained lifting platform.…”

According to the characteristics of loop-connection mechanism based on three quadrilateral elements and scissors elements, a construction method of Bricard-like mechanism based on scissors units and loop-connection mechanism is proposed. First of all, based on the analysis of the motion characteristics of the loop-connection mechanism of three quadrilateral units, a preliminary scheme of adding scissors units is put forward. Secondly, the folding and unfolding characteristics of scissors units are analysed, and different requirements of bars length is put forward according to different characteristics. Finally, the three-dimensional models of Bricard-like mechanism based on scissors units and loop-connection mechanism is established, and its motion modes are analyzed. The proposed construction method can improve the folding ratio of the mechanism and provide some ideas for the design of large-scale folding mechanism.

The deployable bridge based on scissor structures is one of the effective methods to quickly restore traffic after natural and man-made disasters. Scissor structures have the advantages of high storage rate, lightweight, and convenient storage and transportation. However, when scissor structures are used as load-bearing structures, their stiffness and bearing capacity are low. In this study, a three-dimensional deployable bridge based on the cable-strengthened scissor structures was proposed. In addition to rapid expansion, steel cables were used to strengthen scissor structures to improve the stiffness and bearing capacity. Besides, the static loading comparative tests on cable-strengthened scissor structures and traditional scissor structures (cable-free scissor structures) were performed. The results show that the stiffness of the cable-free scissor structure is small, the bending moment of members is large, and the stress distribution is uneven. The stiffness of cable-strengthened scissor structure is significantly improved; the bending moment of members is significantly reduced; and the stress distribution in the member section is more uniform. It is proved that cables can be used to improve the stiffness and load-bearing capacity of scissor structures without affecting the deployability.
