Abstract:The key issue in complex shape building project is the searching for a structure that with high efficiency. Parametric form finding analysis technology has been widely adopted in structural engineering field. Taking complex structure as the project background, the principle and application of parametric form finding analysis were introduced, and the advantages of parametric form finding analysis in the stage of project plan were expounded. With the lessons learned from the encountered problems and the solutions, the results show that the force density method and thrust network analysis are more suitable for complex shape projects, and the particle spring system is more suitable for reticulated dome lighting roof projects and can improve the grid standardization rate.

Keywords:parametric modeling; structural form finding; force density method; thrust network analysis; particle spring system
