Title STUDY ON WIND PRESSURE ACTING ON PNEUMATIC DOME AND INTERNAL PRESSURE CONTROAL TO STABILIZE THE STRUCTURE(Wind tunnel tests for dome models with configuration of the rounded rectangular plan and the minimum surface area)
Author Yuuki Katou,Eizo Maruta
Summary This paper is concerned with wind tunnel experiments for dome models with configuration of the rounded rectangular plan and the minimum surface area and discussed the wind pressure acting solid model made of epoxy resin and flexible models made of silicon of 0.5mm thickness which were made by geometric scale 1/250, and the internal pressure of pneumatic dome or its control method; setting the laser displacement device, in strong winds. In wind tunnel tests which were conducted in the boundary layer flow and uniform flow; using rise ratio f/D=0.15, 0.3 and 0.5, the characteristics of mean, fluctuating, and peak pressure, the estimation to wind loading for pneumatic domes and the internal pressure control method to stabilize the structure are discussed.
