Abstract
The airflow through an unclad lattice structure creates a complex fluid motion which affects the local wind loading of individual members within the framework. Consequently, design loads determined by traditional methods that consider each element as a finite-length member immersed in a uniform flow may be incorrect, particularly at nodal points where the largest disturbance to flow occurs. This paper, therefore, presents details of the wind effects on perpendicular structural intersections composed of either two circular cylinders or two square-section bars.
