Abstract The reliability of connection mode among various segments of bridge pier FRP composite anti-collision sleeve box directly affects the box’s protective performance. Here, the reliability of a butterfly type thumb lock connection structure for composite anti-collision sleeve box used on transition pier of a 2-tower 3-span cable-stayed bridge was analyzed. The material performance tests and the scale model structure tensile strength tests were conducted for the butterfly type connection structure. Then, its orthogonal anisotropy constitutive was defined based on test results. Static and dynamic analyses were performed for the reliability of the connection structure using the software Midas Fea and LS-dyna, respectively. The results showed that the reliability of this type connection structure is good; it can ensure the FRP composite anti-collision sleeve box to give full play to the protective performance.
