Abstract:

An experimental investigation was conducted to clarify the fundamental behaviour of the proposed taut strip wind tunnel model of long span bridge deck systems. The study shows that this method is relatively simple and convenient and yet effective method of investigating the aerodynamic behaviour of long span bridges with the simulation of natural wind turbulence in laboratory scale. Experimental results are compared with the simple theoretical calculation and some aerodynamic characteristics of bridge response in highly developed turbulent boundary layer flow were observed. Effect of scale of turbulence in particular is found to be significant.
