Gust response of a prestressed concrete cable-stayed bridge under cantilever construction

摘要

A concrete cable-stayed bridge constructed by the cantilever construction method is structurally unstable and the gust response of the deck is unavoidable. In this study, gust response analyses of a long spanned concrete cable-stayed bridge during cantilever erection was performed in both a frequency and a time domain analysis using the results of a full scale measurement and the structural safety of the bridge was discussed.
