Abstract
In incineration plants, RC stacks took the place of steel-supported stacks in '70s with the view of improving design appearance. A number of stacks having various shapes other than circle (square, triangle, and so on) have been constructed for the same reason. In order to investigate wind response characteristics of RC stacks having typical shapes, a series of wind tunnel tests were carried out. For the practical design, coefficients of wind force were evaluated based on the test results and in accordance with the method specified in "Recommendations for Loads on Buildings" of AIJ.
