Abstract
Aerodynamic stability of long-span cable-stayed bridge deck is a crucial issue. The bridge deck aerodynamics should be well understood for efficient design of a stable bridge system. In this work numerical simulation is conducted for a pentagonal shaped bridge deck to explore its aerodynamic features numerically. Analytical results are compared with previous experimental work to assess the capability of two-dimensional unsteady RANS simulation to predict the aerodynamic features for this type of deck. It is also tried to clarify the influence of carb location and height on the aerodynamic behavior of the deck. Further goal of this study is to investigate the Reynolds number influence on flow field of the bridge deck.
