Investigation of aerodynamic instability of a thin plate

Abstract

This paper is devoted to methods and principles of investigation of aerodynamic instability of structures. Object of interest is a thin plate. This is an important aspect of the design of large-span structures, bridges and other structures sensitive to wind loads. As Russian standards and Eurocode obliges to check the conditions for the occurrence of galloping, divergence and flutter for a certain class of structures. Modern computing facilities allow to calculate aerodynamic coefficients with high accuracy.
