CHARACTERISTICS OF AERODYNAMIC FORCE ACTING ON AN INCLINED CIRCULAR CYLINDER MODEL DURING WIND-INDUCED VIBRATION

Abstract

Dry cable galloping could be observed in long circular cylindrical members such as stay cables. The authors previously conducted a series of wind tunnel tests where wind-induced response at high wind speed range was observed with an inclined circular cylinder model. In this study, more accurate measurements of the pressure distribution during the response were tried to be obtained. As a result, possible pattern of pressure distribution that cause the response was shown. However measured results sometimes differed from trial to trial, and further study is necessary to have clearer understanding.
