Xác định tải trọng gió bằng thí nghiệm ống thổi khí động cho công tác thiết kế công trình xây dựng tại Việt Nam

Abstract

Buildings in Vietnam are increasingly tall and complex in shape, so it is not feasible to apply current Vietnamese and international wind standards in many cases. The wind tunnel test is a modern and increasingly applied method to determine wind loads for design work in Vietnam. In addition, this test has many meanings in improving design quality and reducing construction costs because the wind load determined by this method is usually about 20% to 30% smaller than the load when determined by the standard. This paper presents the results of applying wind tunnel test over the past 10 years at the Vietnam Institute of Building Science and Technology.
