There are many good resources online for the study of shell structures / those using thinness as a method to form. By following this link to the research group at Princeton University looking at the evolution of German shell structures, you will find a wide and thorough analysis of a large body of work:

Quote from the web site – “Thin Shell structures are intriguing – they seem to float in space and contradict the laws of gravity. They materialize the ideals of engineering by achievening lightness and efficiency through resistance of form.” (Adriaenssens et al. 2013)

Anther wonderful resource is a research group based out of Italy run by Professor Sergio Pone in Naples. Under his direction a diverse group of projects and grid shells have been realized over the last few years. You can see and access the work here:
