Abstract

<p>Recently inconvenience on the community due to infrastructure construction are required to minimize as much as possible. In order to construct temporary bridges quickly, we are considering using the high strength bolted tensile joint with multiple bolt lines. In the bolted tensile joint, it is desirable that the joint surface is flat and completely adhered by the load transmission mechanism. However, since it is a prerequisite to reuse a member of temporary bridges as temporary structures, there is concern that the joint surface may be deformed by repeated use. In this study, the influence of the faying surface conditions and the behavior when filler plates were inserted on the tensile joint was examined with experiment and finite element analysis.</p>
