Abstract
The lack of information, regulatory support and technical know-how, cause a natural diffidence in opting for unconventional design and also represents the greatest obstacle for research sand for a greater use of such structures in conventional buildings. He lightweight construction section is, in fact, the least known and tensile structures still represent a niche market. This work wants to provide an overview of the research aimed at the parametrization of the structural responses and aerodynamic behavior of hyperbolic paraboloid cables net roofs with four different footprints, respectively, square, rectangular, circular and elliptical, focusing on its disclosure to the relative Companies ins this sector, Professional Associations and Universities and hoping an expand of the research sector. In particular, this paper reports data for pressure coefficient acquired in the wind tunnel for wind angle of 0o and the PIV (Particle Image Velocimetry) test, useful to observe the vortex dimension and the flow field.
