Design and Analysis of Emergency Deployable Bridge

Abstract

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-to-loading 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 4×4 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.
