ABSTRACT
ABSTRACT: A buffeting analysis is carried out to evaluate the effect of aerodynamic turbulences on the design of the pylon foundation of a 800 m steel cable-stayed bridge. Both completed and in construction structures are investigated in evaluating the along-bridge-axis bending moment at the tower leg and caisson. Based on current investigations, the maximum bending moment in construction particularly exceeds a design value invoking to find out a measure for suppressing wind-induced vibrations. This study examined a possibility of using buffeting cables or temporal piers as one of feasible measures.
