摘要
Following previous work in which point pressure measurements on isolated low aspect ratio circular structures such as storage bins, silos, and tanks were described, this report describes measurements of wind loads on silos arranged in an in-line group of five. As well as point pressures, area-averaged pressures on wall panels of finite area were carried out using the pneumatic averaging technique. At small spacing between silos, the region of positive pressure on the windward side spans a larger angular sector of the circumference than that for an isolated silo. For wind directions near normal to the line of the silos, high negative mean pressures and high r.m.s. pressures occur near the point of shortest distance to the adjacent silos. © 1990.
