It is desirable that emergency bridges used in large-scale disasters are light in weight so that they can be mounted on vehicles and can be erected quickly. The Acquisition, Technology and Logistics Agency is conducting has been undertaking research on the application of CFRP to the emergency bridges for the Self-Defense Forces with the aim of improving the performance of emergency bridges. Through this study, the strength characteristics of the emergency bridges have been acquired by applying CFRP on the outline design of the assumed bridge, and manufacturing the prototype for the strength examination.
As a result, it was confirmed that the designed assumed bridge can sufficiently withstand the assumed load. In addition, it is affirmed that the weight can be reduced approximately by 26% compared to the conventional aluminum structure.
