【 摘 要 】

How a bridge's expansion joints are connected to the main structure is an important detail, with relevance not only for ease of installation and replacement but also for durability and long-term performance. In the case of steel bridges - or more accurately expressed, in the case of connection to steel surfaces - the challenges tend to be greater than with concreted connections. With steel connections, special attention is required in the design of the expansion joints, and considerably more effort and precision is required on site during installation work. This paper shall describe the particular challenges, and illustrate these, and ways of addressing them, with reference to steel bridge construction and renovation projects.
