Abstract: The design of free-form spatial structures needs to take into account the influence of architectural form andstructural efficiency, involving multiple disciplines. A generative parametric design method for free-form structures wassummarized and proposed, which can automatically and efficiently generate morphology solutions that satisfy both aestheticperformance and mechanical properties under pre-defined conditions through parametric control and developed optimizationalgorithms, and it can generate multiple options for comparison by defining different constraints. The implementationprocess and key technologies of the method were discussed and summarized, and the feasibility and ease of use of themethod was demonstrated through engineering design case. Research shows that the method can be applied to complexforces and boundary conditions, and can achieve multi-objective optimization through special structural analysis, which hashigh applicability;meanwhile, its parametric features can effectively respond to project changes, thus effectively improvingthe design efficiency. This method can effectively help to solve the contradiction of discipline separation betweenarchitecture and structure in the design process, which is a key measure of improving design quality.
