Aeolian Vibration Analysis of Different Node Connectivity Steel Rods

Abstract:

ANSYS is applied to establish finite element model of steel rods with different slenderness ratio (50-250) and differernt node connectivity ([-shaped gusset plate, U-shaped gusset plate, cross-gusset and flange). Modal analysis is used to obtain the first-order natural frequency and VIV formula is used to obtain the first-order critical wind speed of steel rods. Contrasting the simulation value with the corresponding value given by the specification, the results show that there is a great difference between the first-order critical wind speed of most steel rods and the corresponding value given by the specification.
