Influence of Framework and Equipment Interaction on the Wind Loads for Open-Frame Structures

Abstract eng:
The estimation of wind loads on open-frame structures common to industrial process facilities is difficult in part due to the complex interaction effects among the numerous elements (i.e. framing, piping, tanks, and vessels) that are typically exposed to the wind. Recent wind tunnel experiments aimed at identifying important parameters affecting the wind load on such structures have yielded some results relevant to understanding framework/equipment interaction effects. Limited references providing data applicable to this problem recognize that the wind loads on equipment included inside a frame may be reduced from shielding effects. Results from this study confirm this but also illustrate the possibility of increasing wind loads due to lateral interference effects.
