Study on History of Design Standard for Gate

Abstract

Civil engineers have to obtain the consensus of social opinions in order to produce the structures. As the result, the design of structures is reflected by the age and the social conditions.
The level of a functional design, which has a social consensus, is defined as a design standard. The design standard indicates the top levels of technology in every age. A lot of matters are hidden behind the background of the standard. The history of the standard also shows the global tide of technology for an each structure. From a point of view, the history should be put on the trunk of civil engineering history in this sense. However there is no paper that analyze the history of design standards as aproblem of the civil engineering history.
In this paper, as the civil engineering history generalize the authors the history of gate-valve design standards, for example, “Flood-Gate and Iron Pipe Standard” and “Dam and Weir Technical Standard”.
