การพัฒนามาตรฐาน มยผ. 1311-50 สำหรับการคำนวณแรงลมและการตอบสนองของอาคาร

Abstract

The wind load specified in the existing building code No.6, 1984 is not appropriate in many aspects because it is considered only building height. Therefore, the new development of DPT Standard 1311-50 for wind loading calculation and response of buildings in Thailand is financially supported by Department of Public Works and Town & Country Planning. The new standard is more accurate than the building code No.6 because it considers the wind speed zoning, surrounding terrain, building shapes, and dynamic properties. The new standard format is widely used in the international codes. The new standard consists of 3 parts, namely, 1.Wind loading standard for building design, 2.Commentaries to the standard and 3.Numerical examples. Three different approaches for determining design wind loads on buildings are given in the standard, namely, the simple procedure for low- and mid-rise buildings, the detailed procedure for high-rise buildings, and wind-tunnel test procedure.
