SIMULATION REQUIREMENTS FOR ROOF WIND LOADS NEAR THE CORNERS OF LOW BUILDINGS WITH LOW-SLOPE ROOFS

The wind loads that occur near the corners of low-slope roofs on low buildings are problematic in two significant aspects: 1) recent research has shown that wind tunnel models tend to underestimate the peak suction loads acting on very small areas in these regions, and 2) the loads that do occur illustrate most dramatically the severity of spatial and temporal gradients that the wind can produce. These gradients cannot, in general, be reproduced in any full-scale component test machine available today. The purpose of this paper is to highlight these two current areas of difficulty and, in particular, to illustrate the types of loading imposed by the wind and the related shortcomings of current full-scale component test protocols. Although various approaches are being pursued to solve the primary problem (number 2, above), a quick resolution is unlikely, indicating the need for further research.
