Abstract

Methodology for preservation techniques of historical bridges is required in the current situation of increasing demands for preservation of civil engineering heritages. This paper aims to show a guide of techniques of repair and reinforcement of historical steel bridges. We investigated 9 historical steel bridges in Tokyo in the construction works to preserve them and their influence on appearances. The constructions are done for four aims, repair, reinforcement, and addition of new functions and improvement of appearance. General techniques are used in the most construction works for repair and reinforcement. Therefore we arranged the list of techniques of general bridge maintenance in order of aims and structure parts with the notice of using them for historical bridges. On the other hand the constructions for improvement appearances may largely change the impressions so that we also arranged the concepts and methods for them according to the preservation purpose.
