Plastic design methods of portal frames with constant section members of China and Great Britain are compared and discussed. It includes applications, internal force analyses, strength calculations, plastic design conditions, and overall frame stabilities. With the comparison and discussion, some problems that need further research in Chinese plastic design method of portal frames with constant section members are suggested.
Keywords:  portal frame; constant section; plastic design
