Recently, natural desaster such as flood, earthquake occurs frequently in Japan. In order to rebuild the traffic life line earlier after damage, the erection bridge like as temporary bridge of JSDF by the man power only is somewhat suitable. In these cases, the periodic bridge structure which composed of the unit module attached sequentially as well as MGB of JSDF will be relatively rational.
In this study, we tried to find out the skeleton of unit module from the optimization analysis of peropdic bridge structures. Comparing the results between several analytical methods, we present the basic optimum characteristics of the erection bridge.
