ウェブに設置するバイパス部材を適用した鋼I桁下フランジ連結板取替え実験

抄録

One of the methods for replacing steel bridge members is to use attaching additional members to share the stress acting on the replacement members and replace them with new members. In this study, we conducted a steel I girder loading experiment using web bypass members to simulate lower flange connection plate replacement construction, and examined the applicability of the proposed method. As a result, the mechanical behavior of the steel I girder, stress properties, and reinforcing effects of the web bypass members at each construction step were clarified. In addition, we clarified the points that must be kept in mind when designing attaching additional members.
