Aerodynamic dataset for selected doubly curved membrane canopy structures.

Abstract

A dataset of aerodynamic measurements is collected for doubly curved membrane structures as part of a comprehensive experimental testing campaign on wind effects on structural membranes conducted at the WindEEE Dome at Western University, Canada. Common doubly curved membrane geometries - the hypar, ridge valley, arch supported, cone, and umbrella - were tested in isolated instances. The cone geometry was also tested in both a 1 × 3 row and a 3 × 3 group arrangement. All models were tested at a 1:25 scale under atmospheric boundary layer (ABL) flow at angles of attack ranging from 0° to 180° in 10° increments (and 45°, and 135° -depending on the line of symmetry). In addition to ABL, the hypar geometry was subjected to two other distinct flow scenarios: tornado, and downburst. Pressure time series at various tap locations are included in the data. In total, approximately 425 tests were conducted, providing a comprehensive dataset on the aerodynamic behavior of doubly curved structures under wind loads. This experimental data set offers valuable insights for the design and analysis of such structures in architectural and engineering applications and future design guideline developments. Data is available on an open-source dataset Zenodo as part of the ERIES-WENSS project.
