Abstract
In order to ensure that the rescue workers can quickly cross the natural obstacles such as ditches and valleys to enter the disaster area when the traffic facilities are destroyed Seriously by natural disasters, a new type of developable bridge is designed. The design of the bridge is based on the theory of shear hinge and the one-dimensional shear hinge element is used as the basic element. Under the function of dead-weight, the bridge can be unfolded by rope traction. It can be locked into service state after being unfolded to the design position. In this paper, through kinematic simulation and finite element static analysis, the developability and bearing capacity of the developable bridge are verified. The results show that the deployable bridge can meet the design requirements.
