Abstract
Recently some emergency bridges have been developed for road restoration at the time of disaster due to flood, landslide, earthquake, and tsunami. On the other hand, temporary work girders are often used in a construction site, and it is expected that temporary work girders are utilized as the emergency bridge.
In this study, for shortening erection term of temporary work girders, we propose to use the double end plate connection using high strength bolt at the connection of the emergency bridges. The past experiment has confirmed that double end plate connection using high strength bolts can apply bridge main girder connection.
We have applied it to the actual temporary work girders to investigate the structural behavior of the emergency bridge with the double end plate connection through field loading tests.
It was found from the results of the field measurement that the proposed double end plate connection has enough performance, and it can apply to the emergency bridge. This paper also introduces the concept of the emergency bridge with the double end plate connection using high strength bolts.
