summary 
Strained gridshells has been one of the most efficient structure system to cover large spans by lightweight construction. Nevertheless, gridshells structure has been seldom used due to the difficulties in gridshells formfinding and erection, as well as its limitation of morphological possibilities. In this regard, this paper aims to provide an integrated design and fabrication approach for extending the application of strained gridshells into the field of complex geometries. First, a formfinding method for complex gridshells design was put forward and tested taking Enneper surface as examples; secondly, the formfinding result was further developed into a gridshells system consisting of continuous laths, rotatable joints and rigid edge beams, which were optimized afterwards based on the structural simulation result with Finite Element Analysis. Third, the construction difficulties of this system were fully addressed in the robotic fabrication and erection process of a full scale prototype. This research tries to fully combine the structural characteristics of the strained gridshell with digital fabrication technologies to extend the application of strained gridshells into structures with more complex geometries.
