Bridge 0270A is the first bridge project using the steel concrete composite dowel construction method in Australia. The beams selected for this bridge replacement project in the South-West Region of Western Australia consists of halved steel I-girders positioned at the soffit of the beams. This eliminates reinforcement congestion and prestressing. Steel dowels are providing the connection between the steel and concrete sections. Other benefits are reduced bridge beam depth and simplified detailing. This innovative method has proven its structural effectiveness and financial benefits backed up by years of research across Europe. The design and detailing requirements are documented in several design guides and a general building authority approval in Germany. The presentation will discuss the design, manufacturing and construction challenges as well as the identified benefits of this pilot bridge project applying the composite dowel strip design method.
