Recently, the number of steel-concrete composite rigid frame bridges is increasing for short and medium span length in Japan. To make this type of bridge more rational, it is important to ensure a good performance of the rigid connection, which can transfer the load from the steel girder to the abutment. Therefore, a new type of the connection detail with a bearing plate has been proposed by the authors. In this study, effectiveness and applicability of the proposed rigid connection detail was examined by experimental study focusing on the mechanical behavior of it up to the ultimate limit state. As a result, it is found that the proposed connection detail has redundancy and the ultimate strength required.
