Abstract

Wind load is an essential consideration in all building design. It refers to the force of the wind on the building and is a crucial factor in determining the strength and stability of the structure. There are several reasons why it is important to set wind load for calculating building wind. Firstly, wind load is one of the significant loads that a building must withstand. Resistance to wind load is essential to prevent structural damage during high wind events such as storms, hurricanes, and tornadoes. By setting wind load, engineers can determine the wind pressure that the building will experience and design the structure accordingly. Secondly, wind load affects the performance and energy efficiency of the building. The front of the building is typically the primary obstacle to wind load and can have a significant impact on the building's energy consumption. By setting wind load, designers can optimize the building's appearance to minimize energy consumption and improve the building's performance. In this study, we compared and analyzed wind loads calculated using the power law method and the altitude distribution coefficient of wind speed (K_zr) that varies depending on the surface condition. Through this comparison, we were able to analyze the differences in the wake resulting from wind load settings and determine the wind load settings according to the ground environment.
