ABSTRACT
Wind load is not evenly distributed on the surface structure. As such, the average wind load shape coefficient based on load specification will not be able to reflect the actual wind pressure distribution. Wind tunnel tests or wind tunnel numerical simulations are required to determine the actual wind pressure distribution, which provides the basis for structural design. Wind tunnel tests can be omitted when the shapes of super high-rise buildings are relatively regular and simple. For the wind resistance design of structures, the wind pressure distribution can be determined through numerical wind tunnel analysis. It is verified that the simulated wind pressure distribution on the surface structure is similar to the test results, and the error between the numerical analysis and the test is small. The numerical simulation reflects the distribution of wind pressure on the surface of high-rise buildings. On the windward side, it is in good agreement with the test results, with an error of less than 10%. On the crosswind side and leeward side, the numerical simulation results are between the NPL (National Physical Laboratory) and TJ-2 test results. It can meet the accuracy requirements of engineering applications.
