Proposed revisions on wind load provisions for cladding and components in 'Load code for the design of building structures'.

Based on the fundamental theory of wind load determination for the building cladding and components, the comparisons of the provisions associated with the components and cladding from the Chinese and international wind codes are performed. Accordingly, the limitations and corresponding design suggestions for the Chinese load code are presented as follows: in typhoon-prone regions, it is better to divide the statistical analysis of basic wind speed into monsoon and typhoon. On this basis, the basic wind speed in the mixed climate regions can be determined through a combination between two types of wind speed. It is suggested to increase the peak factor to 3.5, which could relatively exactly evaluate the peak fluctuating wind speed. Referring to the international wind codes, the provisions related to the internal wind pressure coefficients should be improved. It is advised to perform the research on the wind directionality effect. Based on the data from meteorological observations and wind tunnel tests for typical buildings, the wind directionality reduction factors, which are adequate for different wind directions and regions in our country, are suggested to propose. It is suggested that the study should be conducted on the area reduction associated with the wind loads for building cladding and components to determine the area reduction factors for different wall and roof zones of typical buildings.
