Wind pressure distribution and non-Gaussian characteristics of a building complex with tree-inspired structures

Abstract

In order to study the characteristics of wind pressure on the surface of a building complex composed of multiple complex curved roofs, the synchronized pressure tests on the rigid models were conducted in an atmospheric boundary layer wind tunnel. The building complex models are composed of three tree-inspired structures and two independent low-rise large-span buildings, and the surface wind pressure time series of three structures with complex curved roofs in the middle of the complex was measured. The results show the distribution characteristics of wind pressure coefficient and high-order moment are significantly affected by the geometries and structures created by various roof configurations. The focus is on the impact of these special complex structures on wind loads, and to summarize some rules that can be referred for designing, and provide some explanations from the perspective of the flow structures generation mechanism.
