The fusion approach of ideological and political education into specialty courses which has a high ratio of the credits determines the success in building up the ideological and political education system. Meanwhile, it is a challenge for the civil engineering teachers of fusing the ideological and political elements into specialty courses seamlessly, and educating students naturally. Design principle of concrete structures was adopted as an example to discuss the aims, strong points and fusion approach of the ideological and political education in specialty courses. In the specialty courses of the civil engineering major, the aims of the ideological and political education can be set in the views of political and national identities, moral characters and professional ethics, as well as academic ambition and scientific spirit. The introduction part of each curriculum always includes the outlines, engineering applications, development history and learning methods of this curriculum. The elements of political and national identities, moral characters and professional ethics can be refined and fused into the introduction part. In the sections of professional knowledges, the academic ambition and scientific spirit elements can be refined and fused into this parts by using the historical literatures and classical experiments in the development of the professional knowledges.
