This paper exhibits the process of conceptual design of the Yongding River Bridge in Beijing,China.The bridge is located at Chang'an Avenue in Beijing,which is lined with prestigious buildings such as Wangfujing shopping area,Tiananmen Square and the Peoples' Congress Hall.This conceptual design considers issues of structural form,mathematical analysis,construction methods,and the relationship of the structure to the site.Specifically,the paper presents how the designers developed a design by starting with an initial aesthetically driven but structurally reasonable decision about form.Several innovative concepts in the design are also described.
