Equipment used to help road users during road maintenance activities is called a flexible bridge. It helps maintain the accessible area of the road when repairs occur. Collapse has occurred sometimes at frame when bending load exceeds the yield strength. In addition to increase the ability of the structure and avoid buckling added a link as damper. Parameters of the absorber are stiffness rate, and elongation of link. A simple square tube beam model supported by a link was created to investigate the bending behavior using finite element analysis. The analysis result showed that beam supported by a link able to reduce buckling moreover provides longer curvature than beam without a link.
