Aerodynamic Coefficients in Building Loading
Wind tunnel tests are designed to measure aerodynamic forces in an object, and then convert these results to quantities that can express such forces in the full-scale object. The conversion of loads from prototypical to full-scale is achieved with aerodynamic coefficients. In guidelines for wind loading of structures, three types of aerodynamic coefficients are commonly used: pressure coefficient (Cp), shape coefficient (Cf), and force coefficients (CF or CM). In this article, we delve deeper into how these coefficients are measured and defined within wind tunnel tests.

Topography Speed-Up Factor
This post presents a comparison of computational fluid dynamics (CFD) performed by AeroSim and experimental results of the topography speed-up factor in a variety of geometries. The developed methodology uses a digital model of the surrounding terrain combined with the earthwork project. In this post we demonstrate that a carefully implemented CFD solution is a viable and more accurate alternative to analytical solutions for the topography speed-up factor. An extended version of this work can be found in the proceedings of the XIV Brazilian Congress of Bridges and Structures.

Assessing Wind Loads on Low-Rise Buildings
In this blog post, we’ll explore AeroSim’s digital wind tunnel results using large eddy simulations (CFD-LES) to study the wind load on the roof of a standard warehouse. The main goal is to assess the feasibility and accuracy of this approach for structural designs of low-rise buildings.
