Code Evaluation of Wind Loading for High-Rise Buildings with Constant and Variable Cross Section in Tehran

Today, high-rise buildings are more welcomed due to the lack of space and the increasing population in large cities. The effect of wind on tall structures in the direction of the wind and its fluctuations are vulnerable. To design a structure against lateral loads such as wind load, the main design criterion should be provided. The importance of the impact of the lateral force increases with the height of the building. Thus, in this type of structures, mainly by wind power, design considerations with height, becomes more complicated. At a certain height, the lateral displacement of the longitudinal structures increases so that the controller's considerations are raised. The characteristics of the wind pressure on the structure are a function of the wind characteristics, structural geometry, and the characteristics of the adjacent region. Typically, standards for structures and buildings that have unusual shapes or positions are not used. The purpose of this study was to investigate the proposed design methods for calculating the wind load in international and domestic standards for the study of long and stable structures in Tehran. In this study, American, European, Japanese and Australian standards have been used for two types of structures, and their results have been compared to those derived from the National Building Regulations of Iran. The results of this study indicate that Iran's national regulations for proposed structures that are considered in Tehran are more conservative than the results of other standards.
