A set of pictures of a 3D printed gridshell inverted umbrella (CANDBRELLA) in the Candela style construction of groined vaulted shells is presented together with the completed hybrid GRIDSHELL-MEMBRANE INVERTED UMBRELLA video to illustrate the concepts of lightweight tensegrity hypar structures. The nanoscale model will be left outdoors to be tested for rain, wind, and snow loading conditions. Let's see how it behaves under environmental typical rain, wind, and snow. One key question I have when working with nanoscale models is: If I were to compare a small scale model to a real size structure say for a 100 mph wind, what would be the corresponding wind velocity to be applied to the nanoscale model to have representative wind pressure on the surface of the hypars in relation to the 100 mph on the real size structure. Would it be higher or lower than the 100 mph and how could I do the correlation? If anyone has any guidelines for this question, it would be great to hear about it.
