To solve the problems of insufficient technical adaptability and complex management caused bythe differences between Chinese and American codes in international projects, this paper takes therelevant codes of concrete structure design in China and the United States as the research object, makes acomparative analysis from the aspects of material performance, load combination, anchorage length oftensile steel bar and construction standards, and studies the influence of code differences on engineeringpractice. The results indicate that there are significant differences in concrete strength test methods, loadpartial coefficients, and anchorage length correction parameters between Chinese and American codes.The anchorage length of American codes is generally higher than that of Chinese codes, and thecalculation process is more refined, while Chinese codes emphasize experience and simplicity. At theconstruction level, Chinese and American codes have different emphases on formwork engineering, steelbar connection, and maintenance requirements. American codes emphasize flexibility and diversification,while Chinese codes focus on structural safety and standardization. The specification difference will leadto the deviation of design redundancy, the conflict of material selection, and the increase of constructionmanagement complexity, which will directly affect the project cost control and compliance risk. Andbased on this, a systematic coping strategy is proposed.
