Abstract
The stream of design form in civil engineering structures, which were constructed in large quantities due to the progress of industrial revolution of 18 century, is tried to systematize and analyze in connection with the architectural design form of the same period. This paper will be the first trial on this subject, whose motivation is (1) to evaluate aesthetic value of civil engineering heritage, (2) to clarify the route to the 20 century design represented by Maillart, Freyssinet, Morandi and Calatrava, and (3) to get a hint for a new design form. The work was based on 459 structures constructed or planned between 1700 and 1945, in which 138 in Great Britain, 119 in France, 75 in Germany, 65 in USA and 62 in Japan. Among the 459, 380 were bridges and 79 were the others. In Chapter 3, overall stream of design form is described separately due to four design styles, that is, Classic, Renaissance, Gothic and 20 Century International. In Chapter 4, difference of design form is discussed due to coutry, site, desingner and their purpose.
