Abstract

Wind loads on a typical low-tunnel structure used in short-term (less than one year) protected cultivations, were studied experimentally and numerically.
Wind pressures were measured by a full-scale field experiment on a cross section of the structure in the case of a transverse wind.
Two-dimensional Computational Fluid Dynamics (CFD) simulations were performed for analysing and interpreting the measurements for the same case of transverse wind.
The boundary conditions were defined to simulate the measured wind characteristics.
The numerically calculated wind pressure distribution is qualitatively similar to the experimental one.
However the negative pressure measured at the tunnel ridge is lower compared to the computational value.
