THE TORSIONAL RESPONSE OF A SUSPENSION BRIDGE STIFFENING TRUSS MODEL TO TURBULENCE AND TO AN UPSTREAM OBSTACLE

A 1:64 scale section model of a recently constructed suspension bridge was tested in smooth flow and turbulent flow with and without an upstream 'obstacle'. Testing was limited to determination of the aerodynamic damping on a model confined to single-degree of freedom torsional motion. The turbulent atmosphere was generated by use of a uniform grid at the test section entrance. The upstream 'obstacle' selected was an almost exact 1:64 replica of a cable-stayed bridge that was basically a flat plate on a narrower box.
