In this paper, the design procedure and construction phases of a post-formed timber
grid-shell are described. For form-finding and verification of structural safety, two different
numerical models were developed. A particle-springs system tool was used to get feed-backs on
the allowable shape and element’s cross section without the use of scale models. The structural
response and the different construction phases of the prototype were analyzed through finite
element modelling, involving material and geometric non-linearities. The mechanical properties
used in the modelling were derived from experimental investigation. To validate the formfinding
procedure, a comparison of the results of numerical analysis and experimental outcomes
is presented.
