THE ACTION OF FLEXIBLE BRIDGES UNDER WIND, 1: FLUTTER THEORY

The action of long-span bridges, notably suspension bridges, under wind has long been of concern. This first of two papers summarizes the pertinent experimental and other prerequisite data and proceeds to the linear dynamic analysis of bridge flutter for bridges having vibration modes that are not necessarily simple, i.e. that may involve motions beyond pure flexure and torsion. A review is made of the energy considerations involved in the assessment of aerodynamic stability. The paper lays the groundwork for the one that follows. /Author/TRRL/
